Product Description
Product Overview
WTA White Tabular Corundum/Alumina is a high-purity alumina material available in standard granular sizes of 0-1mm, 1-3mm, 3-6mm, and 5-10mm, with customized granularity options. This sintered tabular alumina is produced by heating high-grade alumina powder at temperatures exceeding 1900°C, forming distinctive flat, plate-like crystals ideal for demanding industrial applications.
Key Properties & Advantages
High Purity
Minimum 99.2% Al2O3 content ensures superior performance in high-temperature environments.
Excellent Thermal Stability
Maintains structural integrity under extreme heat conditions up to 1900°C.
High Mechanical Strength
Apparent gravity of 3.56g/cm³ provides exceptional durability and resistance to mechanical stress.
Low Porosity
Apparent porosity of 3.5% and water absorption of 1.1% ensure minimal material degradation.
