Product Description
High Density Tabular Alumina Powder
High Density Tabular Alpha Alumina Sintered Tabular Alumina Powder is engineered for demanding industrial applications including steel production, casting operations, petrochemical processing, breathable bricks, ladle linings, and castables.
Product Overview
Tabular corundum, also known as sintered tabular alumina, is a high-purity form of alumina (Al2O3) processed to achieve a unique tabular, flat shape. Produced by sintering high-grade alumina powder at temperatures exceeding 1900°C, this material forms large, flat, plate-like crystals with exceptional performance characteristics.
Key Properties
- High Purity: Minimum 99.2% Al2O3 content
- Excellent Thermal Stability: Withstands extreme temperatures
- High Mechanical Strength: Durable under stress conditions
- Low Porosity: Maximum 5.0% apparent porosity
- Dimensional Stability: Maintains shape under thermal cycling
