Barium waa curiye kiimiko ah oo leh calaamada Ba iyo lambarka atomiga 56. Waa curiyaha shanaad ee kooxda 2, birta dhulka birta ah ee birta ah ee silvery jilicsan. Sababtoo ah falcelinta kiimikaad sare, barium weligeed lagama helin dabiicadda sida curiye xor ah. Hydroxide-keeda, oo loo yaqaan taariikhda casriga ka hor sida baryta, uma dhacdo macdan ahaan, laakiin waxaa lagu diyaarin karaa kuleylka barium carbonate.
Codsiyada: Birta iyo Alloys, Alloys sida; alwaaxyada sunta rasaasta - si loo kordhiyo caabbinta gurguurta; daawaha leh nikkel ee dhimbiil; wax lagu daro birta iyo tuurista birta sida aan waxba lahayn; Alloys leh kalsiyum, manganese, silicon, iyo aluminium sida bir-deoxidizers heer sare ah.Barium waxa ay leedahay dhowr codsiyo warshadeed. Birta ayaa taariikh ahaan loo isticmaali jiray in hawada laga saaro tuubooyinka faakuumka. Waa qayb ka mid ah YBCO (kuwa sare ee heerkulka sare) iyo ceramics electro, waxaana lagu daraa birta iyo birta la tuuray si loo yareeyo xajmiga kaarboonka ee ku dhex jira qaab-dhismeed yar oo birta ah.
Barium, sida bir ahaan ama marka alwaaxinta leh, waxaa loo isticmaalaa in laga saaro gaasaska aan loo baahnayn ee tuubooyinka vacuum, sida tuubooyinka sawirada TV-ga. Barium waxay ku habboon tahay ujeedadan sababtoo ah cadaadiska uumiga hooseeya iyo falcelinta oksijiinta, nitrogen, carbon dioxide, iyo biyaha; waxay xitaa qayb ahaan ka saari kartaa gaasaska sharafta leh iyagoo ku milmaya shabagga crystal. Codsigan ayaa si tartiib tartiib ah u baaba'aya sababtoo ah kor u kaca caanka ah ee LCD tubeless iyo sets balasma.
