Isicelo

I-Barium iyikhemikhali enophawu u-Ba kanye nenombolo ye-athomu engu-56. Iyingxenye yesihlanu kuQembu 2, insimbi ethambile eyinsimbi eyi-alkaline yomhlaba.Ngenxa yokuphinda isebenze kabusha kwamakhemikhali, i-barium ayitholakali emvelweni njengento yamahhala.

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 ibisetshenziswa ngokomlando ukukhafulela 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.
