Physical and Chemical Properties
,

Manganese carbonate, known as MnCO3, is commonly produced in China and is available from reliable suppliers and factories. It appears as rosy triangular rhombic crystals or as an amorphous bright white to brown powder. This compound has a relative density of 3.125 and is characterized by its near insolubility in water. While manganese carbonate is slightly soluble in carbonic acid and common organic acids, it is insoluble in alcohol and liquid ammonia but readily dissolves in dilute inorganic acids.

    Physical and chemical properties

    It remains stable in dry air, and is easy to oxidize to manganese sesquioxide when wet, and its color gradually becomes brown and black.

    When heated, which decomposes and generates carbon dioxide; when heated to boiling with water, which hydrolyzed; when in the boiling potassium hydroxide, manganese oxide gas is formed.

    Function and use

    Manganese carbonate (1)

    Manganese carbonate is a raw material for producing soft magnetic ferrites used in telecommunications equipment, and its particle size can be customized according to customer requirements. It is used for synthesizing manganese dioxide and manufacturing other manganese salts.

    Oxidant for desulfurization
    Pigment for enamel, coatings, and paints
    Additive for fertilizers and feed to improve soil fertility
    Used in pharmaceuticals and welding rod accessories
    Raw material for producing metallic manganese (calcined manganese)

    Packaging, warehousing and transportation

    Manganese carbonate packed in bags lined with polyethylene plastic, each bag weighs 25 kg net. Goods should be stored in a cool, ventilated and dry warehouse. They should be protected from moisture, heat and deterioration.

    During transportation, it is necessary to prevent goods from rain and sun exposure, and handle goods gently during loading and unloading to prevent packaging damage.

    Fire Safety: In case of fire, put out with water, sand and fire extinguisher!
