Ibikoresho bya Shimi
Hariho ubwoko bubiri bwa barium chrome yumuhondo, bumwe ni chromate ya barium [CaCrO4], naho ubundi ni chromat ya barium potassium, ikaba ari umunyu wa chromate ya barium na chromate ya potasiyumu.Imiti yimiti ni BaK2 (CrO4) 2 cyangwa BaCrO4 · K2CrO4.Chromium Barium Oxide ni ifu ya cream-umuhondo, ibora muri aside hydrochloric na aside nitricike, ifite imbaraga nke cyane.Kode mpuzamahanga ya barium chromate ni ISO-2068-1972, bisaba ko ibirimo oxyde ya barium bitari munsi ya 56% naho ibiri muri chromium trioxide ntibiri munsi ya 36.5%.Barium potasiyumu chromate ni ifu yindimu-umuhondo.Kubera potasiyumu chromate, ifite amazi meza.Ubucucike bwayo bugereranije ni 3.65, igipimo cyacyo cyo kugabanya ni 1.9, kwinjiza amavuta ni 11,6%, naho ikigaragara cyacyo ni 300g / L.
Gusaba
Chromate ya Barium ntishobora gukoreshwa nkibara ryamabara.Kuberako irimo chromate, igira ingaruka zisa na zinc chrome yumuhondo iyo ikoreshejwe irangi rya antirust.Chromate ya Barium potassium 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 muburyo bwa chromate anti-rust pigment iboneka muruganda.
