Product Overview
TCH series calcined alumina offers tailored solutions for industrial applications with α-Al2O3content up to 96%, ultra-low impurities (Na2O ≤0.3%, Fe2O3 ≤0.02%), and controlled particle size distribution. Our products are sintered at 1,500°C+ to ensure exceptional thermal stability and mechanical strength, meeting ISO 9001 & REACH standards.
Ultra-High Purity: Al2O3 ≥97% (Up to 99.7% for precision ceramics)
Low LOI: ≤0.2% (Minimized shrinkage during sintering)
Customized Granulometry: D50 1-75μm & SSA 0.1-1.2 m²/g
Phase-Stable: α-Al2O3 ≥90% (Superior hardness & wear resistance)
