IBarium 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 - ukwandisa 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 ephosiweyo 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 siphela ngokuthe ngcembe ngenxa yokunyuka kokuthandwa kwe-tubeless LCD kunye neeseti zeplasma.
