Iipropati zeMichiza
Kukho iindidi ezimbini ze-barium chrome yellow, enye yi-barium chromate [CaCrO4], kwaye enye yi-barium potassium chromate, eyityuwa edibeneyo ye-barium chromate kunye ne-potassium chromate. I-chemical formula yi-BaK2 (CrO4)2 okanye i-BaCrO4 · K2CrO4. I-Chromium Barium Oxide yi-cream-yellow powder, enyibilikayo kwi-hydrochloric acid kunye ne-nitric acid, enamandla aphantsi ngokugqithisileyo. Ikhowudi yomgangatho wamazwe ngamazwe we-barium chromate yi-ISO-2068-1972, efuna ukuba umxholo we-barium oxide ungekho ngaphantsi kwe-56% kunye nomxholo we-chromium trioxide ungekho ngaphantsi kwe-36.5%. I-Barium potassium chromate yi-lemon-yellow powder. Ngenxa ye-potassium chromate, inokunyibilika okuthile kwamanzi. Ubuninzi bayo obusondeleyo buyi-3.65, i-index ye-refractive index yi-1.9, i-oyile yokuxutywa kwayo yi-11.6%, kwaye umthamo wayo ocacileyo ngu-300g / L.
Isicelo
I-Barium chromate ayinakusetyenziswa njenge-pigment yombala. Ngenxa yokuba iqulethe i-chromate, inefuthe elifanayo kwi-zinc chrome yellow xa isetyenziswe kwipeyinti ye-antirust. I-Barium potassium chromate ayinakusetyenziswa njenge-pigment yombala, kodwa ingasetyenziselwa kuphela njenge-pigment echasene ne-rust, enokuthi ithathe indawo ye-zinc yellow. Ngokwembono yendlela yophuhliso, yenye kuphela yeentlobo ze-chromate anti-rust pigments ezikhoyo kwishishini lokugquma.
