Author: Comefrom: Release time:2026/5/14 17:10:56

Chromium oxide green is mainly used as a pigment in paints, glass, ceramics, enamels, and cement. It is also used for metal polishing, the production of art pigments and banknote printing, and for manufacturing ruby (Al2O3  crystals containing a small amount of Cr₂O₃). It is widely applied in the production of precision bearings for instruments, watches, and meters, and can also be used as a catalyst in organic synthesis. And, it is extensively used in refractory materials, pigment production, and paint manufacturing.
