Specifications

Rose colored, diamond shaped crystals, or amorphous light brown powder, relative density

3.125, insoluble in water, but soluble in dilute inorganic acids. Stable in dry air. When wet, it is prone to oxidation, forming manganese trioxide, which decomposes when heated and releases carbon dioxide

Main features

1.High main content, low impurities, potassium, sodium, calcium, and magnesium controlled within 100ppm, and other heavy metals controlled within 10ppm, with stable quality

2.Strict antioxidant treatment has been carried out during the production process, resulting in a light color and low manganese content. The product can be stored for a long time in a sealed environment without oxidation

3.Uniform particle size and the ability to customize product particle size according to customer requirements

Applications

Used for producing chemical reagents, high-purity manganese monoxide, manganese dioxide, manganese trioxide, lithium manganese phosphate battery materials and other high-purity manganese products.

Packaging

Manganese carbonate is packaged in double layers, with food grade polyethylene plastic bags as the inner packaging and plastic woven bags as the outer packaging. Each bag weighs 25 kilograms,

50 kilograms, 1000 kilograms. Printed on the outside of the packaging; Moisture and heat resistance;

protection: The warehouse for storing manganese carbonate should be dry, cool, and not damp or heated to prevent deterioration. Protect from rain and sun during transportation. Handle with care during loading and unloading to prevent packaging damage. Water, sand, and fire extinguishers can be used to extinguish a fire.
