Detailed
Superfine Manganese Sesquioxide Powder Mn2O3
Properties: CAS: 1317-34-6
Appearance: dark crystal, it’s poisonous.
Relative density: 4.5
Molecular Formula: Mn2O3
Molecular weight: 157.87
Solubility: insoluble to water, acetic acid; solute to cold hydrochloric acid, warm nitric acid and warm sulfuric acid.
Deoxidize at 1080℃, its fine dust is flammable. Mn2O3 can be hydrogen disoxidated to Mn2O4 at 230℃, if hydrogen disoxidated above 300℃, it finally get MnO. It can be used as clothe dying material.
