Manganese Nitrate

Details

Manganese Nitrate

Molecular formula: Mn(NO₃)₂

Molecular weight: 400.148

CAS No.: 20694-39-7

EINECS No.: 233-828-8

Appearance: Pink transparent liquid

Physicochemical Properties: 50% concentrated manganese nitrate solution is light red or rosiness transparent liquid. Specific Density: 1.54(20°C). It can be dissolved in water and alcohols. When heated, it will separate out manganese dioxide and emit nitrogen oxide gas. Manganese nitrate hexahydrate is light-rosiness needle-liked lozenge crystal. Melting Point: 25.8°C, Boiling Point: 129.5°C, Density: 1.82(21°C). It is able to dissolve in water and alcohol and decompose into manganese dioxide when temperature ranges from 160°C to 200°C. In addition, it is subject to deliquescence.

Applications and Usages: used as raw material to prepare manganese dioxide, as phosphorizing agent in metals, colorants for ceramics as well as catalysts

Specification : (HG3-1065-77)
