Chemical Properties
Kune marudzi maviri e barium chrome yero, imwe i barium chromate [CaCrO4], uye imwe i barium potassium chromate, inova munyu wemusanganiswa we barium chromate uye potassium chromate.Mushonga wemakemikari ndewe BaK2(CrO4)2 kana BaCrO4·K2CrO4.Chromium Barium Oxide ikirimu-yellow powder, inonyungudika muhydrochloric acid uye nitric acid, ine simba rakaderera rekuita.Iyo yepasi rose standard code ye barium chromate ndeye ISO-2068-1972, iyo inoda kuti zviri mukati mebarium oxide hazvisi pasi pe56% uye zviri muchromium trioxide hazvisi pasi pe36.5%.Barium potassium chromate inonzi lemon-yellow powder.Nekuda kwe potassium chromate, ine kumwe kunyungudika kwemvura.Density yaro i3.65, refractive index i1.9, kunyura kwemafuta i11.6%, uye vhoriyamu yaro inooneka i300g/L.
Application
Barium chromate haigone kushandiswa seruvara pigment.Nekuti ine chromate, ine maitiro akafanana kune zinc chrome yero kana ichishandiswa muantirust pendi.Barium potassium chromate haigoni kushandiswa seruvara rwe pigment, asi inogona kushandiswa chete se anti-rust pigment, inogona kutsiva chikamu che zinc yellow.Kubva pakuona kwemaitiro ebudiriro, ingori imwe chete yemhando dzechromate anti-rust pigments inowanikwa muindasitiri yekupfeka.
