Specification
Application
Manganese powder is an important alloying element in the production of stainless steel, high strength low alloy steel, aluminum manganese alloy, copper manganese alloy and so on.
Storage
Store in a cool, dry and well-ventilated warehouse.
Keep away from fire and heat sources.
The storage temperature should not exceed 30°C.
The packaging is required to be sealed and not in contact with air.
It should be stored separately from oxidants, acids, halogens, chlorinated hydrocarbons, etc., and avoid mixed storage.
Use explosion-proof lighting and ventilation facilities.
It is forbidden to use mechanical equipment and tools that are prone to sparks.
The storage area should be equipped with suitable materials to contain the leakage.
Stability
Avoid contact with humid air, and prohibit contact with acids, alkalis, halogens, phosphorus, and water.
Soluble in dilute acid, manganese reacts with water in water, and can react with halogen, sulfur, phosphorus, carbon and silicon.
During smelting, manganese vapor forms oxides with oxygen in the air.
There are two forms of cube and quadrangle, and has a complex crystal structure.
Electrolytic metal manganese generally contains more than 99.7% of manganese. Pure electrolytic manganese cannot be processed. It becomes a wrought alloy after adding 1% of nickel.
