I-Barium iyikhemikhali enophawu u-Ba kanye nenombolo ye-athomu engu-56. Iyingxenye yesihlanu kuQembu 2, insimbi ethambile eyinsimbi eyi-alkaline yomhlaba. Ngenxa yokusebenza kwayo kabusha kwamakhemikhali, i-barium ayitholakali emvelweni njengento yamahhala. I-hydroxide yayo, eyaziwa emlandweni wangaphambi kwesimanje njenge-baryta, ayenzeki njenge-mineral, kodwa ingalungiswa ngokushisa i-barium carbonate.
Izinhlelo zokusebenza: Insimbi nama-alloys, ama-alloys aphethe; ama-alloys e-lead-tin soldering - ukwandisa ukumelana ne-creep; ingxubevange ene-nickel yama-spark plugs; okungeziwe ensimbi kanye nensimbi ephonswe njenge-inoculant; ama-alloys ane-calcium, i-manganese, i-silicon, ne-aluminium njengama-deoxidizer ensimbi yezinga eliphezulu.I-Barium inezicelo ezimbalwa zezimboni kuphela. Insimbi ngokomlando ibisetshenziswa ukukhukhula umoya kumashubhu e-vacuum. Iyingxenye ye-YBCO (ama-superconductors asezingeni eliphezulu) kanye nezitsha zobumba ze-electro, futhi yengezwa kunsimbi nensimbi ephonswe ukunciphisa usayizi wezinhlamvu zekhabhoni ngaphakathi kwesakhiwo esincane sensimbi.
I-Barium, njengensimbi noma uma ixutshwe ne-aluminium, isetshenziselwa ukususa amagesi angafuneki (udoti) kumashubhu e-vacuum, njengamashubhu ezithombe ze-TV. I-Barium ifanelekele le njongo ngenxa yokucindezela kwayo okuphansi komhwamuko kanye nokusebenza kabusha ku-oksijini, i-nitrogen, i-carbon dioxide, namanzi; ingasusa ngisho nengxenye amagesi ahloniphekile ngokuwancibilikisa ku-crystal lattice. Lolu hlelo lokusebenza lunyamalala kancane kancane ngenxa yokuthandwa okukhulayo kwe-LCD namasethi we-plasma engenamashubhu.
