Manganese Carbonate
Product Description
♦PHYSICAL PROPERTY
The new precipitate is a pink to almost white powder, with rose colored triangular diamond crystals or amorphous bright white brown powder. Relative density 3.125. Almost insoluble in water, insoluble in alcohol and liquid ammonia. Soluble in dilute acids, insoluble in water and ethanol. Slightly soluble in water containing carbon dioxide (i.e. carbonate), it gradually turns light brown in the air. Stable in dry air. When moist, it is prone to oxidation and forms manganese dioxide, which gradually turns brown black and decomposes when heated.
CHEMICAL NAME: Manganese Carbonate
MOLECULAR WEIGHT:114.95
TRANSPORTATION:NO DG
CAS NO.: 598-62-9
FORMULA:MnCO3
HS CODE.:2836999000
♦CHEMICAL PARAMETERS:
Soluble in dilute inorganic acids, slightly soluble in ordinary organic acids. Stable in dry air. When moist, it is prone to oxidation, forming manganese dioxide and gradually turning brown black. When heated, it decomposes and releases carbon dioxide. Hydrolysis occurs when co boiling with water. In boiling potassium hydroxide, manganese hydroxide is generated.

♦APPLICATION
It is a raw material for producing soft magnetic ferrite for telecommunications equipment. Industrial manganese carbonate is widely used as a catalyst for desulfurization, enamel pigment, varnish drying agent, and raw material for manufacturing other manganese salts. It is also used in medicine, mechanical parts, and phosphating treatment. The content of manganese carbonate used as a trace element fertilizer in agriculture can be slightly lower.
