Detailed Introduction
High purity grade
1. Molecular formula:MNCO₃
2. Molecular weight:114.95
3. Property:CAS number: 598-62-9
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
4. Purpose:
Used for producing chemical reagents, high-purity manganese monoxide, manganese dioxide, manganese trioxide, lithium manganese phosphate battery materials and other high-purity manganese products

6. Product Features:
6.1. High main content, low impurities, potassium, sodium, calcium, and magnesium controlled within 100ppm, and other heavy metals controlled within 10ppm, with stable quality< br /> 6.2. 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< br /> 6.3. Uniform particle size and the ability to customize product particle size according to customer requirements
7. Packaging and Storage:
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; The logo and trademark identification are:“ Sanxiang< br /> Storage and 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
Phosphating grade
1. Molecular formula:MNCO ∝
2. Molecular weight:114.95
3. Property:CAS number: 598-62-9
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
4. Purpose:
Mainly used for black phosphating solution, zinc manganese mixed phosphating solution, surface adjustment and other products, as well as mechanical parts, phosphating treatment and other aspects. Telecommunications equipment is used as a raw material for ferrite. Catalysts used for desulfurization, enamel tears, varnish drying agents, manganese salts, and raw materials for catalyst manufacturing

6. Product Features:
1. This product is produced using a two ore method. Compared with traditional manganese carbonate produced from waste manganese solution, this product has higher purity, stable quality, cost savings, and reduced environmental pollution< br /> 2. The raw materials of the product are made of high-quality manganese ore and ammonium bicarbonate, and the phosphating solution is clear and transparent, with stable phosphating effect and quality< br /> 3. The product adopts antioxidant treatment, which can be stored for a long time without being easily oxidized, and has a longer warranty period than ordinary products< br /> 4. When the product is dissolved in phosphoric acid, the speed is fast, the color is transparent without precipitation, and there is no need to heat or add hydrogen peroxide to promote dissolution. The quality of phosphating products is stable
7. Packaging and Storage:
Storage and protection: The warehouse for storing phosphating grade manganese carbonate should be dry, cool, and prevent moisture and deterioration when exposed to heat. The packaging should be kept intact, and it is strictly prohibited to store it together with oxidants, toxic substances, and harmful substances. The storage period should be 12 months from the date of production. Transportation vehicles must be clean and covered to prevent rainwater from getting wet< br /> Packaging: Phosphating grade 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 or can be palletized according to customer requirements. Printed on the outside of the packaging; Manganese carbonate; Words and“ Moisture and heat resistance; The logo and trademark identification are:“ Sanxiang
