Manganese Dioxide Granules
Manganese Dioxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The grades of Manganese Dioxide (MnO2) ranging from MnO2 60% to MnO2 90% in powder as well as Granular form. The powder form ranges from 100 mesh to 300 mesh& Granular Form ranges from 0.4mm to 3 mm.
