Product Description
Electrolytic Manganese Flakes is high-purity metallic manganese in flake form, produced via electrolysis—using manganese ore as raw material, leaching with acid to get manganese sulfate solution, then depositing manganese on the cathode, followed by washing, drying and stripping. Manganese content is usually ≥99.5%.
- High Purity: Mn content ≥99.5% (up to 99.95% for premium grades); ultra-low impurities (S≤0.04%, P≤0.002%, Fe≤0.03%).
- Physical Traits: Silvery-gray, flat flakes (0.5-2mm thick); brittle (easily crushed to powder), with a protective oxide film resisting oxidation.
- Chemical Stability: Resists weak acids/bases at room temperature; reacts with strong oxidizers; effective for deoxidation/alloying at high temperatures.
Applications
- Batteries: Core material for Li-ion battery cathodes (LiMn₂O₄, NCM); high-purity grades boost cycle life and safety.
- High-End Alloys: Added to Al/Mg alloys (e.g., 5052) for corrosion resistance; used in Mn-Cu precision resistors and aerospace titanium alloys.
- Electronics: Produces Mn-Zn ferrites (low magnetic loss) for transformers; used in semiconductor packaging (minimizes signal interference).
- Chemicals/Env Protection: Catalyst for organic synthesis; adsorbent for heavy metal removal in wastewater.
