Overview

Description

Chromium trioxide has α-Al₂O₃ structure, Cr₂O₃ has good stability to acid and alkali, and generally does not react with acid and alkali. The hydroxide of trivalent chromium, Cr(OH)₃, is amphoteric and can react with acids and bases. Soluble in hot alkali metal bromate solution. Insoluble in water, alcohol, acid and alkali. It is extremely stable to light, atmosphere, high temperature and corrosive gases such as sulfur dioxide and hydrogen sulfide. Mainly used for smelting metal chromium and chromium carbide.
