White fused alumina is an important industrial material, widely used in abrasives, refractory materials and ceramics. Its main component is aluminum oxide (Al2O3), which has excellent wear resistance and high temperature resistance.
White fused alumina is made of industrial alumina powder, which is made by arc high-temperature melting (over 2000℃) and then cooled. It has a dense texture, high hardness, and sharp particles, which are suitable for various grinding and polishing operations. The main physical properties of white fused alumina include:
Hardness: Mohs hardness ≥10, which is a very hard material.
Melting point: about 2250℃.
Density: The particle density is between 3.90 and 4.0 g/cm³.
Manufacturing process
The production process of white fused alumina includes the following steps:
Raw material preparation: Use high-purity industrial alumina powder.
Melting: High-temperature melting in an arc furnace.
Cooling and crushing: The molten aluminum oxide is cooled and crushed and shaped.
Screening and magnetic separation: After screening and magnetic separation, iron impurities are removed to obtain products of different particle sizes.
Application areas
White fused alumina is widely used in many industries due to its excellent performance:
Abrasives and grinding tools: used to manufacture grinding wheels, cutting discs, polishing heads, etc.
Sandblasting: used for cleaning, rust removal and surface treatment of metal surfaces.
Ceramics and refractory materials: manufacturing ceramic products and refractory bricks, suitable for high temperature environments.
Precision casting: used as casting sand to improve the surface quality of castings.
