Superfine Manganese Carbonate from China - Reliable Suppliers & Factory for High-Quality Minerals
Physical and Chemical Properties
Formula & ID: 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 as required).
Key Properties: Subjected to ultrafine grinding and classification, it features remarkably improved dispersibility, fluidity and reactivity. Insoluble in water and ethanol, soluble in dilute inorganic acids. Stable when dry; prone to oxidation in humid conditions.
Particle Size Advantages: High specific surface area enables more sufficient reactions and stable performance in battery materials and ferrites.
