Key Feature:
- Ultra-High Temperature Resistance: Withstands continuous operation at temperatures up to 1,380°C, outperforming traditional ceramics and metals in thermal shock resistance.
- Chemical Inertness: Impervious to acids (e.g., H₂SO₄, HCl), alkalis, and organic solvents, ensuring zero contamination during critical material processing.
- Abrasion & Corrosion Resistance: 10× longer lifespan than alumina or zirconia grinding vessels in slurry applications, reducing downtime and replacement costs.
- Customizable Design: Tailored to fit vertical/horizontal mills, sand mills, and attritors, with options for lined or monolithic construction.
Applications:
- 1. Non-Ferrous Metallurgy: Grinding of titanium alloys, tungsten carbide, and rare earth oxides under inert gas protection.
- 2. Chemical Processing: Dispersion of corrosive pigments, catalysts, and battery materials (e.g., LiFePO₄, NCM cathodes).
- 3. Mineral Processing: Ultra-fine grinding of quartz, zircon, and alumina without metal ion contamination.
- 4. Advanced Ceramics: Sintering aids dispersion for Si₃N₄, Al₂O₃, and ZrO₂ ceramic powders at elevated temperatures.
