Product Description
White Corundum Aggregate Raw Materials
Introduction
White Corundum Aggregate Material (also called High Alumina Raw Materials or High Purity Alumina Raw Material) White fused alumina is produced by bayer alumina in an electric arc furnace at high temperatures. The product shows higher hardness and lower toughness than that of brown aluminium oxide. The materials are used to grind high carbon steel, high speed steel and chilled steel. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.
Our White Fused Alumina is electrically fused in arc furnace under the high temperature of above 2000ºC with high grade processed alumina as raw material. It is divided into a variety of particle sizes after crushing, shaping, magnetic separation and iron removing. The WA is dense texture, the hardness is slightly higher than that of Brown Fused Alumina, with high purity, good self-sharpness, strong grinding force, low calorific value, high efficiency, and acid and alkali corrosion resistance, good temperature stability, etc. White corundum abrasives are widely used in refractory materials, ceramic abrasive tools, resin abrasive tools, coated abrasive tools, grinding and polishing, sand blasting, precision casting and other fields.
Features
• Depending on processing: the grain shape is round or splintered
• High hardness of 9 (Mohs)
• Density of 3.95 g/cm³
• Chemical inertness
• High chemical resistance
• Narrow grain size distribution
• Transparent performance in many binding systems

Grain size sand:
· Abrasive tools made of it are suitable for grinding high-speed, high carbon steel,etc.
· It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials,etc.
Characteristics
1. Chemical resistance
2. High-purity alumina, alumina content greater than 99%
3. High-temperature resistance, the Working temperature is 1600 ºC, up to 1800 ºC
4. thermal shock resistance, stable and hard to crack
5. Moulding by casting, has high density
Application :
- The ideal material for refractory products, such as stoppers.
- Grinding and fitting of parts made of different grades of steel.
- For example, when matting, the surface of metal products, glass, and granite is slightly rough.
- Metallurgy - used for the deposition of a non-stick layer of molds. Production of grinding and grinding wheels, bars, and sandpaper.
- Adds to the composition of the production of ceramic insulators for radio components.
