一般說明

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。[1]
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。

應用

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。[2]
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。[3]
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。

We investigate the single-cell reduction of toxic Cr(VI) by the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 (MR-1), an important bioremediation process, using Raman spectroscopy and scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDX). Our experiments indicate that the

Hard coatings for articulating surfaces of total joint replacements may improve the overall wear resistance. However, any coating approach must take account of changes in corrosion behavior. This preliminary assessment analyzes the corrosion kinetics, impedance and mechanical-electrochemical stability of 100
