Chemical Properties
Kune marudzi maviri e barium chrome yero, imwe i barium chromate [CaCrO4], uye imwe i barium potassium chromate, inova munyu wakasanganiswa we barium chromate uye potassium chromate. Iyo kemikari formula ndeye BaK2(CrO4)2 kana BaCrO4·K2CrO4. Chromium Barium Oxide ikirimu-yellow poda, inonyungudika muhydrochloric acid uye nitric acid, ine simba rakaderera rekuita. Iyo yepasi rose yakajairwa kodhi yebarium 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 kweoiri i11.6%, uye inooneka vhoriyamu i300g/L.
Application
Barium chromate haigone kushandiswa seyakavara pigment. Nekuti ine chromate, ine maitiro akafanana kune zinc chrome yero kana ichishandiswa muantirust pendi. Barium potassium chromate haigoni kushandiswa sepigment yemavara, 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.
