General description
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。
Application
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。
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。
采用不同消化技术，以氧化铬 (Cr 2 O 3 ) 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。

The feasibility of stabilizing nickel-laden sludge by a high-temperature NiCr(2)O(4) synthesis process was investigated with different sintering temperatures, salt contents, molar ratios, and reaction atmospheres. The crystalline phases of species were investigated by using an X-ray diffraction, and the surface
