Barium nikintu cyimiti ifite ikimenyetso Ba numubare wa atome 56. Nibintu bya gatanu mumatsinda ya 2, icyuma cyoroshye cya silver metallic alkaline yisi.Kubera imiti myinshi ikora, barium ntabwo iboneka muri kamere nkibintu byubusa.Hydroxide yayo, izwi mumateka yabanjirije kijyambere nka baryta, ntabwo ibaho nkamabuye y'agaciro, ariko irashobora gutegurwa no gushyushya karubone.
Porogaramu: Ibyuma n'amavuta, byitwa amavuta;kurongora - amabati yo kugurisha - kongera imbaraga zo kunyerera;kuvanga hamwe na nikel kumacomeka;inyongeramusaruro yicyuma no guta ibyuma nkibidashiramo;ibinyobwa hamwe na calcium, manganese, silicon, na aluminium nka deoxidizeri yo mu rwego rwo hejuru.Barium ifite inganda nkeya gusa.Icyuma cyakoreshejwe mumateka muguhumeka umwuka mubituba.Nibigize YBCO (ubushyuhe bwo hejuru cyane yubushyuhe) hamwe nubutaka bwa electro ceramics, kandi byongewe kumyuma nicyuma kugirango bigabanye ingano yintete za karubone muri microstructure yicyuma.
Barium, nk'icyuma cyangwa iyo ivanze na aluminiyumu, ikoreshwa mu kuvanaho imyuka idakenewe (gutter) mu miyoboro ya vacuum, nka tereviziyo ya TV.Barium ikwiranye niyi ntego kubera umuvuduko muke wumuyaga hamwe nubushake buke kuri ogisijeni, azote, dioxyde de carbone, namazi;irashobora no gukuramo igice cyimyuka myiza mukuyishongesha muri kasitori.Iyi porogaramu igenda ishira buhoro buhoro kubera kwiyongera kwamamara rya LCD na plasma.
