Isticmaal

Barium waa shey kiimiko ah oo leh astaanta bais iyo lambarka atomikada 56. Waa sheyga shanaad ee Group 2, mid jilicsan oo bir jilicsan oo bir ah oo bir ah. Sababta oo ah falcelinteeda kiimikada ee ugu sarreysa, barium waligeed dabiiciga looma arko inay tahay shey bilaash ah.

Codsiyada: Bir iyo alldos, oo dhaleeceeya alldons-ka; alov-thens-ka horyaalka ah - si loo kordhiyo iska caabinta gurguurta; alloy oo leh nikkel kufsiga ah ee kufsiga; Ku darida birta iyo birta xarkaha sidii loo yaqaan 'toculant'. Aloys oo leh kaalshiyam, manganese, Silicon, iyo aluminium maadaama ay tahay xasaasiyad xasaasiyad heer sare ah.Barium waxay leedahay kaliya dhowr dalabyo warshadeed oo keliya. Birta ayaa taariikh ahaan loo isticmaalay in lagu ciqaabo hawada hawada tuubooyinka vacuum. Waa qayb ka mid ah YBCO (supercontors-ka-sare) iyo dhoobada elektiroonigga ah, waxaana lagu daraa bir iyo bir bir ah si loo yareeyo cabirka badarka kaarboonka miraha miqeynta ee birta.

Barium, oo ah bir ama markii ay ku jiraan aluminium, waxaa loo isticmaalaa in laga saaro gaaska aan loo baahnayn (xargaha) tuubooyinka vacuum, sida tuubooyinka sawirka TV-ga. Barium waxay ku habboon tahay ujeedkan uumi baxa uumiga uumiga ee uumiga iyo firfircoonida uumiga u qabo oksijiinka, nitrogen, kaarboon dioxide, iyo biyo; Xitaa qayb ahaan waxay ka saari kartaa gaaska sharafta leh iyada oo lagu kala diri lahaa suulka crystal.
