China Superfine Manganese Carbonate Suppliers - High-Quality Milled Manganese Carbonate from Factory
Physical and Chemical Properties
Light pink to light brown ultrafine powder with uniform particle size distribution (D50: 1-10 μm normally, adjustable as required).
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.

Function and Use
Applied to cathode materials of lithium manganese iron phosphate and lithium manganate, improving compaction density and electrochemical cycle performance.
Used for high-frequency manganese-zinc ferrites to reduce magnetic loss and enhance magnetic permeability. Ideal for 5G devices and new energy power supplies.
Enables uniform coloring, improves gloss and hardness of ceramic glaze. Weather-resistant pigment for coatings and inks with stable color tone.
Precursor for high-purity manganese salts (nitrate, chloride) and catalyst carrier, delivering higher reaction efficiency.
Packaging, Storage and Transportation
Packaging: 25kg/bag, moisture-proof bags with PE liner. Vacuum packaging available for specific requirements to prevent oxidation.
Storage: Cool, ventilated, dry warehouse. Keep away from moisture, light, and heavy pressure. Separate from acidic/oxidizing materials.
Transportation: Protect from rain and sunlight. Handle gently. Maintain dryness to avoid caking and performance impairment.
Fire Protection: Use water, sand, or fire extinguishers for emergency response.
