Product Specification :
Properties: Black crystal powder. Relative density 4.50. Insoluble in water and acetic acid, soluble in cold hydrochloric acid, hot nitric acid and hot sulfuric acid. Deoxidation at 1080 ℃. Fine dust is combustible. During hydrogen reduction, manganese dioxide is formed at 230 ℃ and manganese oxide (MnO) is formed above 300 ℃. It is prepared by heating manganese dioxide to 530 ~ 940 ℃ in air. The hydrated oxide of trivalent manganese, called manganese brown, is used as a printing and dyeing agent for cloth. It is the raw material and intermediate product of manganese compounds.
Precautions for storage and transportation: store in a dry and ventilated warehouse. Pay attention to moisture, and do not store and transport with acids and oxidants. In case of fire, water, sand and fire extinguisher can be used to put out the fire.
