Tantalum chloride, inta badan loo yaqaantantalum Chloride(TaCl₅), waa cad, ka samaysan inorganic inorganic oo ka ciyaara door laxaad leh oo ka ciyaara kiimikooyinka horumarsan iyo warshadaha elektiroonigga ah. Qaabkeeda saafiga ah (formula TaCl₅) waa budo cad waxayna u adeegtaa sidii walxaha bilawga ah ee kiimikooyin badan oo tantalum ku salaysan. TaCl₅ si heer sare ah ayey u falceliseysaa - si sahal ah ayey hawada ugu shubtaa si ay u sameyso tantalum oxychloride iyo ugu dambeyntii tantalum pentoxide - marka waa in had iyo jeer lagu maamulaa hoostaanhydrous(biyo la'aan) xaaladaha. Dareenka qoyaankan macneheedu waxa weeye in TaCl₅ sida caadiga ah lagu kaydiyo oo lagu raro weel xidhan oo qallalan.
Maqaalkan, waxaan sahamineynaalaba mawduuc oo waaweynMarka hore, maamulaha isticmaalka tantalum chloride ee warshadaha iyo cilmi-baarista; iyo labaad, sida TaCl₅ loo soo saaro lagana soo saaro alaabta ceeriin. Dooddu waxay noqon doontaa mid ay heli karaan kuwa aan takhasuska ahayn, oo leh sharraxaad cad iyo talooyin ku saabsan halka jaantuska ama miiska laga yaabo inuu caawiyo fahamka. Meel kasta oo ay suurtagal tahay, waxaanu tixraaci doonaa ilaha farsamada si aan u hubinno saxnaanta, oo ay ku jiraan macluumaadka suugaanta alaabta gaarka ah.
Isticmaalka Muhiimka ah ee Tantalum Chloride
Tantalum pentachloride waa kiimiko kala duwandhexeiyo kicin. Sababtoo ah waa xoog badanLewis acid(Aqbalaaha-lammaanaha elektarooniga ah), TaCl₅ waxaa loo adeegsadaa fal-celinno synthetic iyo hababka agabka kala duwan. Qaar ka mid ah codsiyada muhiimka ah waxaa ka mid ah:
● Kataliye ku abuurma organic:TaCl₅ waxay u shaqeysaa sidii kicinta korantada oo kale sida aluminium chloride (AlCl₃). Waxaa loo isticmaalaa si kor loogu qaado falcelinta gaarka ah, tusaale ahaan polymerizations amaFriedel-Farsamonooca acylations iyo alkylations. Waxa loo shaqaaleeyay sidii kicinta polycyclotrimerization ee alkynes gaar ah (falcelinta samaynta polymer-ka) iyo diyaarinta xeryahooda chloro-aryloxide.
● Hordhac u ah tantalum oxides iyo oxychlorides:Sababtoo ah TaCl₅ hydrolyzes si ay tantalum oxychloride (TaOCl₃) ka dibna tantalum pentoxide (Ta₂O₅), si joogto ah ayaa loo isticmaalaa in lagu sameeyo alaabtaas. Ta₂O₅ waa oksaydh-dielectric fure ah oo loo isticmaalo capacitors iyo dahaarka qiime-sare leh. Ficil ahaan, TaCl₅ waxa loo rogi karaa (iyada oo lagu daro biyo ama ammonia) oxides tantalum oo aad u saafi ah ama ammonium oxychloride oo ka dibna lagu qiyaaso oksaydhyada. Dariiqan waa hal sabab oo TaCl₅ ay u tahay quud muhiim u ah warshadaha tantalum.
● Dhigista walxaha semiconductor:Warshadaha microelectronics, TaCl₅ waxaa loo isticmaalaa gaas horudhac ahKaydinta uumiga kiimikada (CVD)iyoDhigista lakabka atomiga ah (ALD)aflaan khafiif ah oo tantalum ka kooban. Tusaale ahaan, uumiga TaCl₅ waxaa lagu falcelin karaa ammonia ama balaasmooyinka nitrogen si loo dhigo filimada khafiifka ah ee tantalum nitride (TaN), walxo loo isticmaalo sida xannibaadaha faafinta ama korantada ee wareegyada isku dhafan. Waxa kale oo loo isticmaalaa in lagu shubo filimada tantalum pentoxide for capacitors. Degganaanshaheeda deegaanka koloriintu waxay ka dhigaysaa mid ku habboon hababkan heerkulka sare leh.
● Elektrooniga iyo Alloys:Ugu dambeyntii, inta badan TaCl₅ la soo saaro ayaa loo rogaabiraha tantalumsi loogu isticmaalo qaybaha elektarooniga ah. Capacitors Tantalum - capacitors yar yar oo loo isticmaalo telefoonada gacanta, laptops, iyo elegtarooniga kale - waxay ku tiirsan yihiin Ta₂O₅ nadiif ah oo sare (oo laga soo qaatay TaCl₅) sida dielectric. TaCl₅ lafteedu waa dhagax jaranjaro: waa la dhimi karaa (tusaale ahaan sodium ama aluminium) si ay u soo saarto budada tantalum ee wanaagsan, taas oo ka dibna laga dhigayo capacitors iyo alloys heerkul sarreeya. Marka la soo koobo, TaCl₅ waamuhiim u ah samaynta birta tantalumsidaas darteedna dhammaan warshadaha tantalum capacitor. (Miiska ama jaantuska socodka oo soo koobaya u beddelka TaCl₅ ee birta, oxide, iyo alaabada nitride waxay ka caawin kartaa akhristayaasha inay arkaan waddooyinkan.)
Marka la soo koobo, tantalum pentachloride waxaa loo isticmaalaa meel kasta oo aad u saafi ah xeryahooda tantalum ama filimada looga baahan yahay. Waxay awood labadabahababka kiimikada organic(sida kicinta iyo wakiilka koloriinta) iyohababka alaabta(dhigista filimada, isku-darka oksaydhyada). Marka loo eego xogta soo saaraha, TaCl₅ "waxay u shaqeysaa sidii qalab bilow ah oo loogu talagalay xeryahooda kutlada octahedral M₆" waxayna ku lug leedahay sameynta tantalum(V) oxychloride iyo pentoxide. Dabeecaddeeda elektiroonigga ah (electron-jecel), oo la mid ah kuwa kiciyaasha caadiga ah sida AlCl₃, waxay hoosta ka xariiqaysaa doorkeeda kimistariga horumarsan.
Sida Tantalum Chloride loo diyaariyey
Soo saarista tantalum pentachloride waxay ku lug leedahay koloriinta tantalum nooc ka mid ah. Waxaa jira laba dariiqo oo waaweyn: koloriinaynta birta tantalum, iyo koloriinta xeryahooda tantalum (sida caadiga ah oksaydhyada). Xaaladaha oo dhan, falcelinta waa in lagu sameeyaa meel qalalan, oo aan oksijiin lahayn. Nidaamyada aasaasiga ah waa:
● Koloriinta tooska ah ee tantalum biraha:Birta tantalum oo si fiican loo kala qaybiyay (badanaa faylgarayn ama budo) ayaa lagu kululeeyaa qulqulka gaasta koloriin. Heerkulka qiyaastii 170-250 °C, koloriintu waxay la falgashaa birta si ay u samayso uumiga TaCl₅:
2 Ta+5 Cl2⟶2 TaCl5.2 \, Ta + 5 \, Cl_2 \ garrow midigta dheer 2 \, TaCl_5.
Fal-celintan ka-baxsan waxay si degdeg ah ugu beddeshaa birta koloriinta. Ficil ahaan, tantalum-ka waxaa la geliyaa foornada ama reactor-ka iyo gaaska Cl₂ ayaa lagu dul shubaa heerkul la kantaroolo. Uumiga TaCl₅ ka soo baxa ayaa markaa lagu ururiyaa dareere ama adag marka uu qaboojiyo. (Habka la xidhiidha waxay isticmaashaa gaaska hydrogen chloride (HCl) halkii Cl₂, laakiin tani waxay u baahan tahay heerkul sare - qiyaastii 400 ° C - si loo kiciyo falcelinta.)
● Koloriin aan toos ahayn (laga bilaabo oksaydhyada):Badanaa, birta tantalum ee nadiifka ah ee nadiifka ah lama heli karo ama waa qaali. Taa baddalkeeda, qofku wuxuu ku bilaabi karaa tantalum pentoxide (Ta₂O₅), kaas oo ku badan macdanta. Ta₂O₅ waxaa loo rogi karaa TaCl₅ iyadoo la isticmaalayo wakiilka koloriinta sidathionyl chloride (SOCl₂). Falcelintu waa:
Ta2O5+5 SOCl2→240∘C2 TaCl5+5 SO2.\text{Ta}_2\text{O}_5 + 5\,SOCl_2 \xrightarrow{240^\circ\text{C}} 2\,TaCl_5 + 5\,SO_2.
Habkan, Ta₂O₅ adag waxaa lagu qasaa dareere SOCl₂ oo la kululeeyo (qiyaastii 240 °C). SOCl₂ waxay si wax ku ool ah ugu beddeshaa oksaydhka chloride, iyada oo soo saarta gaasta sulfur dioxide ka soo saar. Dariiqan aan tooska ahayn waa mid faa'iido leh marka lagu shaqeynayo budada oksaydhka waxayna dhalin kartaa TaCl₅ saafi ah.
Labada hab ee kor ku xusan waxay soo saaraanTaCl₅ gaas, taas oo markaa ay tahay inay noqotocufan oo la safeeyey. Ficil ahaan, gaasta koloriin ku jirta waa la qaboojiyaa si TaCl₅ dareeraha (dhibcaha karkarinta ~ 239 °C). Distillation inta badan waxaa loo isticmaalaa in lagu kala saaro TaCl₅ iyo wax kasta oo wasakh ah ama walxaha karkarin hoose. Tusaale ahaan, marka shaybaadhka la isku dhex abuurayo, waxa laga yaabaa in qofku uu gaaska u dhex maro dabin qabow ama kondensers taxane ah. Uumiga ka dib, alaabta waa la qalajiyey (kuleyl si tartiib ah hoostiisa vacuum) si meesha looga saaro raadadka qoyaanka. Tani waxay keenaysaa cad cad oo nadiif ah oo sarreeya. (Amiiskasoo koobidda hababkan isku-dhafka ah - liiska fal-celiyeyaasha, xaaladaha, iyo alaabta - waxay kaa caawin kartaa in la barbardhigo waddooyinka dhinac-dhinac ah.)
● Soo saarista warshadaha ee macdanta:Marka la eego baaxadda weyn, tantalum waxaa inta badan laga helaa macdanta sida tantalite ama coltan, kuwaas oo ka kooban labadaba tantalum iyo niobium oxides. Hal geeddi-socod warshadeed, xoogga macdanta waxaa lagu daraa kaarboon (coke) waxaana lagu falceliyaa gaasta koloriin heerkulka sare. Carbochlorination-kani waxa uu oksaydhyada u beddelaa koloriin kacsan. Markii hore, isku dhafka titanium, niobium, iyo chloride tantalum ayaa sameysma oo isku ururisa dareere la yiraahdo "titanium-niobium-tantalum oxichloride." Dareerahan qayb ahaan waa la miiray: marka hore titanium tetrachloride (TiCl₄) waa laga saaray (karray 136 °C), taasoo ka tagaysa inta badan niobium iyo chlorides tantalum. Isku darka haray ayaa markaa koloriin lagu sii kordhiyaa (haddii loo baahdo) si loogu beddelo oxychloride kasta pentachlorides. Ugu dambeyntii, niobium chloride (NbCl₅) iyo tantalum chloride (TaCl₅) waxaa lagu kala saaraa jajabyo jajab ah, maadaama TaCl₅ ay ku karkariso 239 °C iyo NbCl₅ at 248 °C. Natiijada kama dambaysta ah waa la nadiifiyey TaCl₅. TaCl₅an waxaa badanaa lagu falceliyaa ammonia aqueous si ay u soo dejiso ammonium tantalum fluoride ama oxychloride, taas oo marka calcination ay dhaliso Ta₂O₅ ultra-pure. Nuxur ahaan, TaCl₅ waxay u adeegtaa sidii dhexdhexaadiye sifaynta tantalum ee macdanta. Ashaxda socodkamuujinta tillaabooyinkan - laga bilaabo macdanta ceeriin ilaa TaCl₅ ilaa oxide - waxay faa'iido u yeelan doontaa akhristayaasha si ay u sawiraan habka warshadaha.
Marka la soo koobo, tantalum chloride waxaa lagu soo saaraa halogenation ee birta tantalum ama iskudhisyada. Koloriinta tooska ah ee Ta birta ee leh Cl₂ waa dariiqa shaybaadhka ugu fudud, halka hababka warshaduhu ay inta badan isticmaalaan koloriin-ku-kulul sare ee tantalum oxide-ku- uruurinta kaarboon (carbochlorination) ama walxaha kale ee koloriinta. Gaaska TaCl₅ waa la isku ururiyey oo lagu nadiifiyaa si nadiif ah oo sarreeya. Waxa xusid mudan, mid ka mid ah qoraallada farsamada ee soo saaraha ahi waxa ay xoogga saarayaan in TaCl₅ loo isticmaalo “kloriinta walxaha organic” iyo sidii “dhexdhexaad kiimikaad” si loo soo saaro birta tantalum ee saafiga ah, iyada oo hoosta ka xariiqaysa doorkeeda sida reagent iyo dhexdhexaad muhiim ah labadaba.
Soo koobid
Tantalum chloride(TaCl₅) waa dhexdhexaad kiimiko oo fure u ah warshadaha tantalum. Waxaa si aad ah loo isticmaalaa sida awax laga bilaabosi loo sameeyo xeryahooda kale ee tantalum (oxides, nitrides, biraha) oo u adeega sida aLewis acid kicinfalcelinta kiimikaad ee gaarka ah. Codsiyada caadiga ah waxay u dhexeeyaan qalabka elektiroonigga ah (tantalum capacitors, filimaanta khafiifka ah ee semiconductor) ilaa isku-darka dabiiciga ah ee horumarsan. Sababtoo ah TaCl₅ waa qoyaan xasaasi u ah oo daxalka leh, maaraynta waxay u baahan tahay xaalado qallalan oo adag.
Soo saarista TaCl₅ waxay ku lug leedahay koloriinta tantalum nooc ka mid ah. Shaybaadhka, tani waxay ka dhigan tahay ka falcelinta Ta birta ama oksaydhka leh koloriin (ama ilo koloriin). Warshadaha, waxa ay la macno tahay isticmaalka koloriin-ku-kulul-sare ee macdanta macdanta, inta badan kaarboon, oo ay ku xigto kala-saarid. Dhammaan dariiqyada waxay u baahan yihiin nadiifin taxaddar leh si loo go'doomiyo TaCl₅ saafi ah oo meesha looga saaro alaabada.
Fahamka labadabaadeegsadaiyohababka wax soo saarkaTantalum chloride waxay lagama maarmaan u tahay qadarinta doorka ay ku leedahay tignoolajiyada casriga ah. Marka la isku daro tafaasiisha isku-darka kiimikada ee codsiyada la taaban karo (iyo bixinta agabka aragga marka ay caawinayso), akhristayaasha waxay arki karaan sida xaruntan u muuqata dahsoon ay dhab ahaantii u tahay linchpin oo ah agabka tantalum-ku-salaysan ee elektiroonigga, kimistariga, iyo wixii ka dambeeya.
