Chromium(III) Oxide Hydrate Description
Chromium(III) oxide hydrate is a highly insoluble thermally stable chromium source suitable for glass, optic and ceramic applications. Chromium oxide is a green, hygroscopic solid found in nature as the rare mineral eskolaite.
Chromium(III) oxide hydrate has good spraying process performance and its spraying process specification is wide. It is less sensitive to overheating during spraying, and the coating is not easy to crack when local overheating occurs. The sprayed layer is very dense, and the bonding strength with the substrate is high, and it is easy to be machined such as grinding and polishing.
