三氧化二铬主要用作涂料、油墨和陶瓷的绿色颜料。以硫磺还原铬酸钠为原料,合成了亚铁酸盐。三氧化二铬也被称为氧化铬。在对动物进行的各种消化试验中,它通常被用作标记物。 应用 在固相反应中用于形成新的三元氧化物 CrVMoO 7 ,这应该在选择性氧化中得到应用。并测定了其晶体结构。采用不同消化技术,以氧化铬 (Cr2O3) 作为测定牛粪中铬含量的标准。它也被用作一项研究中的消化率标记物。用于形成新型三元氧化物 CrVMoO7 的固态反应,此三元氧化物可用于选择性氧化。 Chromium(III) oxide is also referred to as chromic oxide. It is commonly employed as a marker in various digestion assays conducted on animals. Chromium(III) oxide is mainly used as a green pigment in paints, inks and ceramics. On a commercial scale, it is synthesized by the reduction of sodium chromate with sulfur.
