Hordhac
Nuxurkabariumqolofka dhulka waa 0.05%. Macdanta ugu caansan ee dabiiciga ah waa barite (barium sulfate) iyo engegan (barium carbonate). Barium waxaa si weyn loogu isticmaalaa qalabka elektarooniga ah, ceramics, daawada, batroolka iyo qaybaha kale.

1.Warshadaha Elektarooniga ah
Mid ka mid ah isticmaalka muhiimka ah ee barium waa sida heter si looga saaro gaaska raadadka ee tuubooyinka faakuumka iyo tuubooyinka sawirada. Waxaa loo isticmaalaa xaaladda filimka geter-ka uumi-baxa, shaqadeeduna waa inay abuurto isku-dhisyo kiimiko ah oo leh gaaska ku hareeraysan aaladda si looga hortago cathode-ka oksaydhka ee tuubooyin badan oo elektaroonig ah inay ka falceliyaan gaasaska waxyeellada leh iyo waxqabadka sii xumaanaya.
Aluminium aluminium nikkel geter waa caadi uumi, kaas oo si ballaaran loo isticmaalo in tuubooyinka gudbinta awoodda kala duwan, tuubooyinka oscillator, tuubooyinka camera, tuubooyinka sawirada, tuubooyinka qoraxda iyo qalab kale. Tuubooyinka sawirada qaarkood waxay isticmaalaan nitrided barium aluminium getters, kaas oo sii daaya qadar badan oo nitrogen ah falcelinta uumi-baxa. Marka xaddi badan oo barium ah uumibaxo, sababtoo ah isku dhafka molecules nitrogen, filimka barium-ka barium-ku kuma dhajin shaashadda ama maaskarada hooska laakiin wuxuu ku ururiyaa qoorta tuubada, taas oo aan lahayn wax-qabad wanaagsan oo wanaagsan, laakiin sidoo kale waxay hagaajinaysaa iftiinka shaashadda.
2.Warshadaha dhoobada
Karbonatka Barium waxaa loo isticmaali karaa dhalaalid dhoobo ah. Marka barium carbonate ay ku jirto dhalaalka, waxay sameyn doontaa casaan iyo guduud.
Barium titanate waa sheyga aasaasiga ah ee matrixka ceramics ee taxanaha titanate waxaana loo yaqaanaa tiirka warshadaha dhoobada elektiroonigga ah. Barium titanate waxay leedahay dielectric joogto ah, khasaaro dielectric hooseeya, ferroelectric aad u fiican, piezoelectric, iska caabin cadaadis iyo guryaha dahaarka, iyo waxaa si ballaaran loo isticmaalaa in qaybaha xasaasiga ah dhoobada, gaar ahaan heerkulka wanaagsan heerkulka wanaagsan (PTC), capacitors dhoobada multilayer (MLCCS), walxaha thermoelectric, piezoelectric ceramics, sonar, bandhigay kristal paneli, walxaha korantada korantada. agabka xusuusta, agabka isku dhafan ee polymer-ku-salaysan iyo dahaarka.
3. Warshadaha rashka
Cusbada Barium (sida barium nitrate) waxay ku gubataa midab cagaar-huruud ah oo dhalaalaya waxaana badanaa loo isticmaalaa in lagu sameeyo rashka iyo ololka. Rashka cad ee aan aragno waxaa mararka qaarkood lagu sameeyaa barium oxide.
4.Saliida Soo Saarista
Budada Baryte, oo sidoo kale loo yaqaan barium sulfate dabiiciga ah, ayaa inta badan loo isticmaalaa sidii wakiilka miisaanka ee dhoobada qodista saliidda iyo gaaska. Ku darida budada barite ee dhoobada waxay kordhin kartaa cuf-jiidka gaarka ah ee dhoobada, isku dheelitirka miisaanka dhoobada iyo cadaadiska gaaska ee dhulka hoostiisa, sidaas awgeedna waxay ka hortagtaa shilalka qarxinta.
5.Xakamaynta cayayaanka
Barium carbonate waa budo cad oo aan biyo ku milmin balse ku milma aashitada. Waa sun waxaana badanaa loo isticmaalaa sida sunta jiirka. Kaarboonayumka Barium waxa uu kula falcelin karaa acid hydrochloric ee casiirka gastric si uu u sii daayo ion barium sun ah, taasoo keenta falcelin sun ah. Sidaa darteed, waa in aan ka fogaannaa in si kama' ah loo cuno nolol maalmeedka.
6. Warshadaha caafimaadka
Barium sulfate waa budo cad oo aan ur lahayn oo aan dhadhamin taas oo aan ku milmin biyaha ama aashitada ama alkali, sidaa darteed ma soo saarto ion barium sun ah. Inta badan waxaa loo isticmaalaa dawo caawiye ah oo loogu talagalay baaritaannada raajada ee baaritaannada sawir-qaadista caloosha, oo badanaa loo yaqaan "barium food imaging".
Baadhitaannada shucaaca waxay isticmaalaan barium sulfate inta badan sababtoo ah waxay nuugi kartaa raajooyinka mareenka caloosha iyo mindhicirka si ay u koraan. Ma laha saameyn farmaajo lafteeda waxaana si toos ah looga soo saari doonaa jirka ka dib marka la nuugo.
Codsiyadani waxay muujinayaan kala duwanaanshahabiraha bariumiyo muhiimadda ay u leedahay warshadaha, gaar ahaan warshadaha elektaroonigga ah iyo kuwa kiimikaad. Astaamaha gaarka ah ee jireed iyo kiimikaad ee birta barium waxay ka dhigaan door lama huraan ah warshado badan.
