Molar mass:86.9368 g/mol

Appearance:Brown-black solid

Density:5.026 g/cm3

Melting point:535 °C (995 °F; 808 K) (decomposes)

Solubility in water:insoluble

Magnetic susceptibility (χ):+2280.0·10−6 cm3/mol

Crystal structure:Tetragonal, tP6, No. 136


The predominant application of MnO2 is as a component of dry cell batteries: alkaline batteries and so called Leclanché cell, or zinc–carbon batteries. Approximately 500,000 tonnes are consumed for this application annually. Other industrial applications include the use of MnO2 as an inorganic pigment in ceramics and in glassmaking.
