Mawu Oyamba
Zomwe zili mubariumm'matumbo a dziko lapansi ndi 0.05%. Mchere wambiri m'chilengedwe ndi barite (barium sulfate) ndi witherite (barium carbonate). Barium amagwiritsidwa ntchito kwambiri mu zamagetsi, zoumba, mankhwala, mafuta ndi zina.

1.Makampani Amagetsi
Chimodzi mwazinthu zofunika kwambiri zogwiritsira ntchito barium ndikuchotsa mpweya wotuluka m'machubu a vacuum ndi machubu azithunzi. Amagwiritsidwa ntchito ngati filimu ya evaporative getter, ndipo ntchito yake ndi kupanga mankhwala opangidwa ndi mpweya wozungulira mu chipangizocho kuti ateteze cathode ya oxide mu machubu ambiri a electron kuti asagwirizane ndi mpweya woipa ndi kuwonongeka kwa ntchito.
Barium aluminiyamu faifi tambala getter ndi wamba evaporative getter, amene chimagwiritsidwa ntchito zosiyanasiyana machubu kupatsira mphamvu, machubu oscillator, machubu kamera, machubu zithunzi, machubu osonkhanitsa dzuwa ndi zipangizo zina. Machubu ena azithunzi amagwiritsa ntchito ma nitrided barium aluminium getters, omwe amatulutsa kuchuluka kwa nayitrogeni mu evaporative exothermic reaction. Pamene kuchuluka kwa barium kumasanduka nthunzi, chifukwa cha kugunda ndi mamolekyu a nayitrogeni, filimu ya getter barium sichitsatira chinsalu kapena chigoba cha mthunzi koma imasonkhanitsa pakhosi la chubu, lomwe silili ndi ntchito yabwino ya getter, komanso imapangitsanso kuwala kwa chinsalu.
2.Makampani a Ceramic
Barium carbonate angagwiritsidwe ntchito ngati mbiya glaze. Pamene barium carbonate ili mu glaze, imapanga pinki ndi yofiirira.
Barium titanate ndiye maziko oyambira a titanate series electronic ceramics ndipo amadziwika kuti mzati wamakampani opanga zida zamagetsi. Barium titanate imakhala ndi ma dielectric okhazikika, kutayika kwa dielectric otsika, ferroelectric, piezoelectric, kukana kukakamiza ndi kutchinjiriza, ndipo imagwiritsidwa ntchito kwambiri pazinthu za ceramic, makamaka kutentha kokwanira kutentha kwa thermistors (PTC), multilayer ceramic capacitors (MLCCS), thermoelectric element, piezoelectric ceramics, sonar, crystal radiation electrodetection element zipangizo, polima opangidwa ndi nsanganizo zipangizo ndi zokutira.
3.Fireworks Viwanda
Mchere wa Barium (monga barium nitrate) umayaka ndi mtundu wobiriwira wachikasu ndipo nthawi zambiri umagwiritsidwa ntchito popanga zozimitsa moto ndi zoyaka moto. Zozimitsa moto zoyera zomwe timaziwona nthawi zina zimapangidwa ndi barium oxide.
4.Kutulutsa Mafuta
Baryte ufa, womwe umadziwikanso kuti barium sulfate wachilengedwe, umagwiritsidwa ntchito ngati cholemetsa pamatope obowola mafuta ndi gasi. Kuthira ufa wa barite m’matope kungawonjezere mphamvu yokoka ya matope, kulinganiza kulemera kwa matope ndi mphamvu ya pansi pa nthaka ya mafuta ndi gasi, ndipo motero kupeŵa ngozi zophulika.
5.Kuthana ndi tizirombo
Barium carbonate ndi ufa woyera umene susungunuka m'madzi koma umasungunuka mu asidi. Ndi poizoni ndipo nthawi zambiri amagwiritsidwa ntchito ngati poizoni wa makoswe. Barium carbonate imatha kuchitapo kanthu ndi hydrochloric acid mumadzi am'mimba kuti itulutse ma ayoni a poizoni, kuchititsa chiphe. Choncho, tiyenera kupewa kumwa mwangozi pa moyo watsiku ndi tsiku.
6.Makampani azachipatala
Barium sulphate ndi ufa woyera wopanda fungo komanso wopanda kukoma womwe susungunuka m'madzi kapena mu asidi kapena zamchere, motero sutulutsa ayoni a barium oopsa. Nthawi zambiri amagwiritsidwa ntchito ngati mankhwala othandizira pakuwunika kwa X-ray pakuwunika kwa m'mimba, komwe kumadziwika kuti "barium meal imaging".
Kuyeza kwa radiation kumagwiritsa ntchito barium sulphate makamaka chifukwa imatha kuyamwa ma X-ray m'mimba kuti ipangike. Zilibe pharmacological zotsatira palokha ndipo adzakhala basi excreted ku thupi pambuyo ingestion.
Mapulogalamuwa akuwonetsa kusinthasintha kwazitsulo za bariumndi kufunika kwake m'makampani, makamaka m'mafakitale amagetsi ndi mankhwala. Zapadera zakuthupi ndi zamankhwala zachitsulo cha barium zimapangitsa kuti ikhale yofunika kwambiri m'mafakitale ambiri.
