I-Barium yikhemikhali enesimboli engu-Ba kunye nenombolo ye-athomu engu-56. Yinto yesihlanu kwiQela lesi-2, isinyithi esithambileyo esisisilivere sealkaline yomhlaba. Ngenxa ye-reactivity ephezulu yeekhemikhali, i-barium ayifumaneki kwindalo njengento yamahhala. I-hydroxide yayo, eyaziwayo kwimbali yangaphambili njenge-baryta, ayinakwenzeka njengeminerali, kodwa inokulungiswa ngokufudumeza i-barium carbonate.
Usetyenziso: Isinyithi kunye ne-alloys, ii-alloys ezithwele; i-lead-tin soldering alloys - ukunyusa ukuxhathisa kwe-creep; i-alloy nge-nickel yeeplagi ze-spark; ukongeza kwintsimbi kunye nentsimbi yokuphosa njenge-inoculant; i-alloys ene-calcium, i-manganese, i-silicon, kunye ne-aluminium njenge-deoxidizers yensimbi ephezulu.I-Barium inezicelo ezimbalwa zoshishino kuphela. Isinyithi kudala sisetyenziselwa ukukhupha umoya kwiityhubhu zevacuum. Iyingxenye ye-YBCO (i-high-temperature superconductors) kunye neekeramics ze-electro, kwaye zongezwa kwintsimbi kunye nentsimbi yokuphosa ukunciphisa ubungakanani beengqolowa zekhabhoni ngaphakathi kwe-microstructure yesinyithi.
I-Barium, njengesinyithi okanye xa ixutywe ne-aluminiyam, isetyenziselwa ukususa iigesi ezingafunekiyo (i-guttering) kwiityhubhu ze-vacuum, ezifana neetyhubhu zemifanekiso yeTV. I-Barium ifanelekile kule njongo ngenxa yoxinzelelo oluphantsi lomphunga kunye nokusebenza kwakhona kwi-oxygen, i-nitrogen, i-carbon dioxide, kunye namanzi; inokususa iigesi ezibalaseleyo ngokuyinyibilikisa kwileti yekristale. Esi sicelo siyanyamalala ngokuthe ngcembe ngenxa yokunyuka kokuthandwa kwe-tubeless LCD kunye neeseti zeplasma.
