Milled Superfine Manganese Carbonate from China - Quality Suppliers & Factory Products
🧪 Physical and Chemical Properties
Molecular Formula: MnCO₃
Molecular Weight: 114.95
CAS No.: 598-62-9
Appearance: Light pink to light brown ultrafine powder with uniform particle size distribution (D50: 1-10 μm normally, adjustable).
Properties: Subjected to ultrafine grinding and classification, it features remarkably improved dispersibility, fluidity and reactivity. It shares the same chemical properties as manganese carbonate, being insoluble in water and ethanol, soluble in dilute inorganic acids. It is stable when dry but prone to oxidation in humid conditions.
Particle Size Advantages: It has a high specific surface area, enabling more sufficient reactions and more stable performance in applications such as battery materials and ferrites.
