I-Barium yindawo yekhemikhali enesimboli ye-ba okanye inombolo yeatomic 56. Yeyona nto yesihlanu kwiQela 2, i-Alkaline ye-Alkaline ye-Alkaline yentsimbi. Ngenxa yokungasebenzi kakuhle kwemichiza, i-barium ayifumaneki kwindalo njengento yasimahla. I-hydroxide yayo, eyaziwa kwimbali yangaphambi kwale mihla njengeBaryta, ayikho njengeminerali, kodwa inokulungiswa ngokufudumeza i-barbonate.

Izicelo: Intsimbi kunye ne-alloys, ithwele isabelo; i-tin ethengiselweyo ye-alloys-ukwandisa ukumelana nokunganyangeki; i-alloy nge-nickel yeplagi ye-spark; yongeza kwintsimbi kwaye ikhuphe i-iron njenge-inoculant; I-alloys enee-calcium, i-manganese, i-silicon, kunye ne-aluminium njenge-deoxizers ephezulu yentsimbi.I-Barium inezicelo ezimbalwa zemveliso. Isinyithi siye sasetyenziselwa umoya wokukrokrela umoya kwiityhubhu. Yinxalenye ye-YBCO (amaqondo aphezulu amaqondo aphezulu e-Superconders) kunye ne-electro ceramics, kwaye yongezwa kwintsimbi kwaye ikhuphe i-iron ukunciphisa ubungakanani beengqolowa zekhabhoni ngaphakathi kwentsimbi.
I-Barium, njengentsimbi okanye xa i-Aluminiyam, isetyenziselwa ukususa igesi engafunekiyo (i-gutter) ukusuka kwi-tubes vacus, ezinjengeempompo zomfanekiso weTV. I-Barium ilungele le njongo ngenxa yoxinzelelo oluphantsi lwe-vapor kwaye iphinde isebenze kwioksijini, i-nitrogen, ikhabhoni, diokside, namanzi; Ingakwazi nokususa igesi ngokuyinxenye ngokuyekisa kwi-crystal lattle. Esi sicelo sinyamalala ngokuthe ngcembe ngenxa yokuphakama kwe-LCD ye-LCD ye-LCD kunye neseti yePlasma.
