pyrolusite
Molecular formula :
MW :
CAS :

nature : MnO2 63.2% Mn. Quartet crystal. Crystal was fine needle-like or columnar; Most of the massive, powder-like clusters. The color of all black marks. Crystallization of a good half-metallic sheen. But higher hardness; Aphanitic block and powder-like person, glossy bleak, low hardness, extreme pollution hand. Five density around. Pyrolusite mainly derived from the deposition. Manganese ore, which is a very common mineral. For the refining of manganese, preparation manganese steel and various manganese compounds.
