Imiti
Hariho ubwoko bubiri bwa barium chrome umuhondo, imwe nirium chromate [cacro4], naho irindi ni potasium potasate chromate, nikintu cyumunyu wa bariya na potasim chromate. Imiterere yimiti ni Bak2 (CRO4) 2 cyangwa bacro4 · k2cro4. Chromium Barium oxide ni ifu yumuhondo, gushonga muri aside hydrochloric na aside ya mydrochloric na aside ya nitric, hamwe nimbaraga nke cyane. Kode mpuzamahanga isanzwe ya Bariimi ni iso-2068-1972, bisaba ko ibikubiye muri barium oxide itarenze 56% nibikubiye muri triyoium trioxide ntabwo ari munsi ya 36.5%. Ikibuga cya potasium chromate ni ifu yumuhondo-umuhondo. Kubera indamu ya potasiyumu, ifite amazi menshi. Ubucucike bwarwo ni 3.65, indangagaciro zayo ni 1.9, kwinjiza amavuta ni 11.6%, kandi bigaragara ko hari amajwi yihariye ni 300g / l.
Gusaba
Barium chromate ntishobora gukoreshwa nkingurube. Kuberako irimo chromate, ifite ingaruka nkizo kuri zinc chrome umuhondo iyo ukoreshwa muri antigero. Ikibuga cya potasium chromate ntigishobora gukoreshwa nkigipapuro cyamabara, ariko kirashobora gukoreshwa gusa nkisomu ya anti-rist, ishobora gusimbuza igice cya zinc umuhondo. Dukurikije uburyo bwiterambere ryiterambere, nimwe gusa muburyo butandukanye bwa chromate anti-rist pigment iboneka mu nganda zo gupfuka.
