China Suppliers of Milled/Superfine Manganese Carbonate - High-Quality Factory Production
Physical and Chemical Properties
Molecular Formula: MnCO₃
Molecular Weight: 114.95
CAS No.: 598-62-9
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).
Light pink to light brown ultrafine powder with uniform particle size distribution (D50: 1-10 μm normally, adjustable as required).
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.

Function and Use
New Energy Battery Materials: The ultrafine high-activity powder is applied to cathode materials of lithium manganese iron phosphate and lithium manganate, improving compaction density and electrochemical cycle performance.
Soft Magnetic Ferrite: Used for high-frequency manganese-zinc ferrites to reduce magnetic loss and enhance magnetic permeability. It is suitable for electronic components such as 5G communication devices and new energy power supplies.
High-end Ceramics & Coatings: It enables uniform coloring, and improves the gloss and hardness of ceramic glaze. As a weather-resistant pigment in coatings and inks, it features good dispersibility and stable color tone.
Fine Chemical Industry: Serves as the precursor for high-purity manganese salts (manganese nitrate, manganese chloride) and catalyst carrier, delivering higher reaction efficiency.

Frequently Asked Questions
What are the advantages of ultrafine Manganese Carbonate powder?
The ultrafine powder offers a higher specific surface area, which significantly improves reactivity, dispersibility, and fluidity compared to standard grades. This leads to more stable performance in battery and ferrite applications.
Can the particle size (D50) be customized?
Yes, while the standard D50 range is 1-10 μm, we can adjust the particle size distribution according to specific customer requirements and application needs.
Why is vacuum packaging used for this product?
Manganese Carbonate is prone to oxidation in humid conditions. Vacuum packaging is used for specific products to prevent oxidation, moisture absorption, and caking during storage and transit.
Is this product suitable for 5G communication components?
Yes, it is highly suitable for high-frequency manganese-zinc ferrites used in 5G devices, as it helps reduce magnetic loss and enhances magnetic permeability.
What are the solubility characteristics of Manganese Carbonate?
It is insoluble in water and ethanol but easily soluble in dilute inorganic acids, where it reacts to form corresponding manganese salts.
How should the product be stored to ensure longevity?
It should be stored in a cool, dry, and ventilated warehouse. It is critical to keep it away from acidic materials, oxidizing agents, and high-moisture environments to prevent contamination and degradation.
