Ibikoresho bya Shimi
Hariho ubwoko bubiri bwa barium chrome yumuhondo, bumwe ni barium chromate [CaCrO4], ubundi ni barium potassium chromate, ikaba ari umunyu wuzuye wa barium chromate na chromat potasiyumu. Imiti yimiti ni BaK2 (CrO4) 2 cyangwa BaCrO4 · K2CrO4. Chromium Barium Oxide ni ifu ya cream-umuhondo, gushonga muri aside hydrochloric na acide ya nitric, hamwe nimbaraga nke cyane. Kode mpuzamahanga ya barium chromate ni ISO-2068-1972, isaba ko ibirimo oxyde ya barium bitari munsi ya 56% naho ibiri muri chromium trioxide ntibiri munsi ya 36.5%. Barium potassium chromate ni ifu yindimu-umuhondo. Kubera potasiyumu chromate, ifite amazi make. Ubucucike bwacyo bugereranije ni 3.65, igipimo cyacyo cyo kugabanya ni 1,9, kwinjiza amavuta ni 11,6%, kandi ingano yacyo igaragara ni 300g / L.
Gusaba
Barium chromate ntishobora gukoreshwa nkibara ryamabara. Kuberako irimo chromate, igira ingaruka zisa na zinc chrome yumuhondo iyo ikoreshejwe irangi rya antirust. Chromate ya Barium potasiyumu ntishobora gukoreshwa nkibara ryamabara, ariko irashobora gukoreshwa gusa nka pigment irwanya ingese, ishobora gusimbuza igice cyumuhondo wa zinc. Urebye uko iterambere ryifashe, ni bumwe gusa mu bwoko bwa chromate anti-rust pigment iboneka mu nganda zitwikiriye.
