High-Purity Calcined Kaolin Powder for Industrial Applications
High-Purity Calcined Kaolin Powder for Industrial Applications
Engineered for performance and consistency, our High-Purity Calcined Kaolin Powder is a premium-grade industrial mineral filler and functional additive—ideal for demanding ceramic, coating, rubber, plastic, and refractory applications.
Key Features & Benefits
- Exceptional Purity: ≥99.5% Al₂O₃ + SiO₂ content; ultra-low impurities (Fe₂O₃ < 0.03%, TiO₂ < 0.02%) ensure superior whiteness (≥92.0% ISO brightness) and thermal stability.
- Precise Calcination Control: Fully dehydroxylated at optimized temperature (950–1050°C), delivering consistent particle morphology, high surface area (18–22 m²/g), and excellent dispersibility.
- Industrial-Grade Consistency: Strict batch-to-batch control per ISO 9001 manufacturing standards; available in multiple particle size distributions (D50: 1.8–2.5 µm) and surface treatments (untreated or silane-modified).
- Global Compliance Ready: REACH-compliant, non-hazardous, RoHS-friendly, and certified for food-contact indirect use (FDA 21 CFR 173.350 compliant upon request).
Typical Applications
- Ceramic Kaolin: High-strength whiteware, sanitaryware, and technical ceramics requiring low shrinkage and enhanced green strength.
- Coatings & Inks: High-opacity, smooth-finish architectural paints, automotive basecoats, and gravure flexo inks.
- Rubber & Plastics: Reinforcing filler for EPDM, SBR, and engineering thermoplastics—improving tensile strength, dimensional stability, and dielectric properties.
- Refractories & Foundry: Binder-free core sands and high-temperature linings with excellent hot strength and low thermal expansion.
