Product Description
High-purity white alumina ceramics (Al2O3 ≥99.8%) with 2-3μm crystal size. Ideal for electric vacuum tube shells (dry pressing) & extruded ceramics. Excellent electrical insulation & sinterability.
Low-Sodium Alpha Aluminum Oxide for Advanced Technical Ceramics
Our high-purity white alpha aluminum oxide powders are engineered for demanding ceramic forming processes. With controlled crystal sizes (0.5-3.0μm) and ultra-low sodium content, they are the ideal choice for applications ranging from electric vacuum tubes to extruded wear-resistant parts.

Application-Specific Product Guide
Key Features & Benefits by Series
TM-CB Series (e.g., TM-CB, TM-CB-V)
Superior Electrical Insulation: Essential for high-performance electric vacuum applications.
Excellent Grindability & Uniformity: 2-3μm original crystals ensure a uniform microstructure and superior surface finish after grinding.
Ideal for Metallization: The composition and structure provide an excellent substrate for subsequent metal coating processes.
TM-CC Series (e.g., TM-CC-1, TM-CC-2)
Enhanced Sinterability: Fine, reactive particles promote densification at optimized temperatures.
High Fired Density: Results in ceramic bodies with high mechanical strength and durability.
Uniform Shrinkage: Narrow particle size distribution ensures predictable and consistent dimensional control during firing.
