(1) Diyaarinta barium okide
Biyo tayo sare leh waa in marka hore la soo xushaa oo la sabbaysaa, ka dibna bir iyo silikon waa laga saaraa si loo helo wax ka badan 96% barium sulfate. Budada ore leh cabirka walxaha wax ka yar 20 mesh ayaa lagu qasay budada dhuxusha ama batroolka cabitaannada culayska ee 4: 1, iyo la dubay 1100 ℃ ℃ a a℃ furn Sallate barium-ka waxaa lagu yareeyaa barium sulfide (oo loo yaqaan "ash madow"), iyo xalka barium-ka ee lagu helo waxay ku qoran tahay biyo kulul. Si loogu beddelo barium sulfide-ka barium roonka roobka, kartoonada sodium ama kaarboon-ka kaarboon-dioxide waxay u baahan tahay in lagu daro xalka aquir-ka barium-ka bari ee bari. Dieum okide waxaa laga heli karaa isku-darka kaadida bari ee kaadida kaarboonka oo ku soo kabashada dusha sare 800 ℃. Waa in la ogaadaa in barium oxide loo dejiyo si loo sameeyo barium peroxide 500-700 ℃, iyo barium peroxide waxaa loo geyn karaa si loo sameeyo barium oxide 700-800 ℃. Sidaa darteed, si looga fogaado soosaarka barium peroxide, sheyga xisaabinta ayaa loo baahan yahay in la qaboojiyo ama lagu dubiyo iyadoo la raacayo ilaalinta gaaska intt.
(2) Qaabka dhimista alumininicmic-ka si loo soo saaro barium metallic ah
Sababo ka kooban waxyaabo ka duwan, waxaa jira laba ficil oo ah aluminium yareynta yar yareude:
6Bayo → 2Al → 3Bo • Al2o3 + 3Ba ↑
Ama: 4Bao + 2Al → bao • al2o3 + 3Ba ↑
At 1000-1200 ℃, labadan falcelinta waxay soo saaraan barium aad u yar, sidaa darteed bamka faaruq ah si loogu wareejiyo uumiga barium aaga soonaha ah si jawaab-celinta loo sii wado si uu u sii wado dhanka midig. Hadhaaga ka dib markii jawaab celintu ay sun tahay oo u baahan tahay in la daaweeyo ka hor intaan la tuurin.
Diyaarinta xeryahooda barium ee caadiga ah
(1) Habka diyaarinta ee loo yaqaan 'barium carbound'
Habka loo yaqaan 'kaarboon'
Habka kaarboonku wuxuu inta badan ku lug leeyahay isku qasidda iyo dhuxusha saamiga gaar ah, ku burburinaya meel rolo ah oo ku dhex jira oo ka dhigeysa 1100-1200 ℃ si loo helo barium sulfide. Kaarboon dioxide waxaa lagu soo rogay xalka barium-ka bari-ka si loo helo kaarboon, falcelintuna waa sida soo socota:
Bas + Co2 + H2O = Baco3 + H2s
Slan-yaraha loo yaqaan 'Barium Carboarn' waa la jajabiyey, la maydhay oo faaruqmay oo la qalajiyey oo la jajabiyey oo la jajabiyey 300 ℃ si loo helo sheyga kaarboon ee barium-ka dhammaaday. Qaabkani waa mid fudud oo ka socda geedi socodka iyo qiimaha hooseeya, sidaa darteed waxaa qaatay inta badan soo-saareyaasha badankood.
② Qaabka goynta
Baraum sulfide iyo hawada ammonium ee loo yaqaan 'probbonate' oo loo yaqaan 'preathopsition', falcelintuna waa sida soo socota:
BAL + (NH4) 2CO3CO3 = Baco3 + (NH4) 2s
Ama koloriin bariude-ka barides waxay ka falcelisaa kaarboon potassium, iyo falcelintu waa sida soo socota:
Bacl2 + K2co3 = Bacato3 + 2kl
Shayga laga soo helay falcelinta ayaa markaa la maydhay, la sifeeyey, qalalan, iwm. Si loo helo sheyga kaarboon ee barium-ka dhammaaday.
③ Barium Carbonate Helbocate
Budada karbaashka barium-ka ayaa ka falceliyay milix ammonia si ay u soo saarto cusbo barium, iyo kaarboon ammonium-ka ah dib loo warshadeeyay. Cusbada Barium-ka lagu daro ee loo yaqaan 'ammonium carbonate' si loo daadiyo kaarboon-ka barium-ka, oo la sifeeyo oo la qalajiyo si loo sameeyo sheyga dhamaaday. Intaas waxaa sii dheer, khamriga hooyada ee helay waa la warshadeyn karaa. Falcelintu waa sida soo socota:
Baca3 + 2hl = bacl2 + h2o + co2
Bacl2 + 2nh4oh = ba (oh) 2 + 2nh4cl
BA (Oh) 2 + CO2 = Bacato3 + H2O
(2) habka diyaarinta ee Barium Titanate
① Qaabka Wajiga adag
Baranium Titanute waxaa lagu heli karaa xisaabinta bari-ka iyo dioxium-ka ixide, iyo waxyaabo kale oo kale waa lagu dhejin karaa. Falcelintu waa sida soo socota:
Tio2 + Baco3 = batio3 + co2 ↑
Habka CopReco
Baram chloride iyo tatnium tetrachloride-ka iyo titrachloride waa isku dhafan yihiin oo kala diri waayaan tiro isku mid ah, oo lagu kululeeyaa 70 ° C, ka dibna lagu daro dhagxiga bari oxolate [batio (c2O4) 2 • 4h2) oo la qalajiyey, oo la qalajiyey, oo la qalajiyey, iyo Ka dib Prororolyzed si uu u helo barium Titanate. Falcelintu waa sida soo socota:
Bacl2 + ticl4 + 2h2Co4 + 5H2o = batio (c2O4) 2 • 4H2O ↓ + 6hll
Batio (c2O4) 2 • 4H2O = batio3 + 2Co2 ↑ + 2Co ↑ + 4h2o
Ka dib markii lagu garaacay aashitada metatitanic, xalka loo yaqaan 'barium chublonade' waxaa lagu daraa hawada amarada jir -tiinka ee ammonium-ka waxaa lagu daraa kareyso si ay u abuurto xog-uruurinta kaarboon-ka barida iyo metatitanic acid, kaas oo loo xisaabiyo in la helo sheyga. Falcelintu waa sida soo socota:
Bacl2 + (NH4) 2CO3CO3 = Baco3 + 2nh4cl
H2Tio3 + Baco3 = Batio3 + Co2 ↑ + H2O
(3) Diyaarinta barium chloride
Geedi socodka wax soo saarka ee barium chloride inta badan waxaa ka mid ah habka asaasiga ee hydrochloric, habka kaarboon ee loo yaqaan 'Helboon', hab kasium chlorium iyo habka chlorium chloride iyo habka chlosium chloride 'iyo habka chlosium chloride-ka iyo hababka loo yaqaan magloride' iyo hababka chlonium chloride.
① Qaabka acid hydrochloric. Marka barium sulfide lagu daaweeyo hydrochloric acid, falcelinta ugu weyn waa:
Bas + 2hci = bacl2 + h2s ↑ + q
Habka loo yaqaan '②barium carbonbote'. Waxaa lagu sameeyay Baarium Carboon (kaarboon barium ah) sida sheyga ceyriinka ah, ficil celinta ugu weyn ayaa ah:
Baca3 + 2hci = bacl2 + CO2 + H2O
Habka loo yaqaan '③carbon-ka'
Saamaynta barium ee caafimaadka aadanaha
Sidee bariums u saameeyaa caafimaadka?
Barium ma aha cunsur muhiim u ah jirka bini-aadamka, laakiin waxay saameyn weyn ku leedahay caafimaadka aadanaha. Barium waxaa laga yaabaa in lagu soo bandhigo barium inta lagu jiro mindhigga barium, scredeynta, waxsoosaarka, iyo adeegsiga xeryahooda bari. Barium iyo xeryahooda waxay jidhka geli karaan maraacinta neef-mareenka, dheef-shiidka, iyo maqaarka waxyeelloobay. Sunta barium-ka shaqada waxaa badanaa keena neef-mareenka neefsashada, oo ku dhacda shilalka shilalka inta soosaarka iyo isticmaalka; Sunta barium-ka ee aan shaqada ahayn waxaa sababa by dheefshiidka marinka dheef-shiidka, oo inta badan sababa cilad shil ah; Xeryaha yar ee dareeraha ah ayaa lagu nuugi karaa maqaarka dhaawaca ah. Sunta bariute-ka bariga ayaa waxaa sababa dhabarka shilalka.
Isticmaalka caafimaad
(1) Idaacadaha cuntada barium
Idaacadaha cunnada barium, ayaa sidoo kale loo yaqaan sawir-qaad dheef-shiidka, waa qaababka baaritaanka bari ee barium sulfate si ay u muujiyaan inay jiraan nabaro ku dhaca mareenka dheef-shiidka ee hoos imaatinka raajada. Idaacadaha cunnada barium waa mid afka ah oo afka ah oo ah wakiilka isbarbar dhigga, iyo Salfium Salluium Salluium-ka ee loo yaqaan 'Salfid' oo loo adeegsado wakiilka isbarbar dhiga biyaha iyo buskudka oo aan lagu nuujin doonin xabka caloosha, sidaa darteed waa asal ahaan asal ahaan aan sun ahayn bini-aadamka.
Marka loo eego baahiyaha ogaanshaha kiliinikada iyo daaweynta, is-baaritaanka cunnada ee caloosha, caloosha caloosha ee caloosha, oo ah cunnada barium-ka caloosha, caloosha caloosha, iyo caleemaha caloosha ee casharka ee canamatada.
Salaanta barium
Wadooyinka soo-gaadhista soo-gaadhista
Barium waxaa lagu soo bandhigi karaabariumInta lagu jiro macdanta barium, screting, iyo wax soo saar. Intaas waxaa sii dheer, barium iyo xeryahooda si ballaaran ayaa loo istcimaalaa. Saldhigga caadiga ah ee saxaanta ee baaritaanka waxaa ka mid ah kaarboon-ka barium, barium chlotide, bari Sulfide, barium framside, iyo barium), iyo bariudes. Qaar ka mid ah baahiyaha maalinlaha ah ayaa sidoo kale leh barium, sida barium sulfide ee daroogada dhoofinta. Qaar ka mid ah wakiillada xakameynta cayayaanka ee cayayaanka qaarkood ama kuwa loo yaqaantuntides-ka qaarkood ayaa sidoo kale ku jira cusbo barium ah oo lagu cusbo sida Barium chloride iyo barium carbonate.
