In nature, manganese dioxide is present as mineral pyrolusite (soft manganese ore).
It is a brown-black powder, which is practically insoluble in water. Even with cold sulfuric or nitric acid, no reaction takes place.
One of the essential, classic applications is the alkaline and zinc-carbon batteries (primary and / or dry cell batteries).
As one catalytic action, manganese dioxide reacts with hydrogen peroxide, releasing or producing oxygen.
There are also numerous uses as oxidizing agents, e.g. in organic synthesis, as a component in sealants or even in pyrotechnics.
Added to this are the glass, enamel and ceramics industries.
In bags of 25kg or 50kg, in big bags of 1,000kg or 1,200kg
Usually available from EU warehouse, but not always in every package!
