Barium chinhu chemakemikari chine chiratidzo Ba uye nhamba yeatomu 56. Icho chinhu chechishanu muBoka 2, simbi yakapfava yesirivha yealkaline yepasi.Nekuda kweiyo yakakwira makemikari reactivity, barium haisati yawanikwa mune zvakasikwa sechinhu chemahara.Yayo hydroxide, inozivikanwa munhoroondo yemazuva ano isati yasvika sebaryta, haina kuitika semaminerari, asi inogona kugadzirirwa nekupisa barium carbonate.
Applications: Metal uye alloys, kutakura alloys;lead-tin soldering alloys - kuwedzera kurwisa kunokambaira;alloy ne nickel ye spark plugs;kuwedzera kune simbi uye simbi yakakandwa seinoculant;alloys ane calcium, manganese, silicon, uye aruminiyamu seyepamusoro-giredhi simbi deoxidizers.Barium ine mashoma maindasitiri ekushandisa.Simbi yagara ichishandiswa kutsvaira mweya mumachubhu evacuum.Icho chikamu cheYBCO (high-temperature superconductors) uye electro ceramics, uye inowedzerwa kusimbi uye simbi yakakandwa kuderedza saizi yekabhoni tsanga mukati meiyo microstructure yesimbi.
Barium, sesimbi kana kuti yakasanganiswa nealuminium, inoshandiswa kubvisa magasi asingadiwi (guttering) kubva mumachubhu evacuum, semachubhu emifananidzo yeTV.Barium inokodzera chinangwa ichi nekuda kwekuderera kwayo kwemhute uye reactivity kune oksijeni, nitrogen, carbon dioxide, uye mvura;inogona kunyange kubvisa chikamu magasi akanaka nekuanyungudutsa mucrystal lattice.Ichi chishandiso chiri kunyangarika zvishoma nezvishoma nekuda kwekuwedzera kukurumbira kweiyo tubeless LCD uye seti yeplasma.
