White aluminium oxide powder, also known as white fused alumina powder or white corundum powder, is produced from high-quality alumina through electric arc furnace melting, 눌러 터뜨리는, grinding and precision classification. With excellent hardness, chemical stability and controlled particle-size distribution, it is widely used by manufacturers that require consistent abrasive performance and clean surface processing.
Unlike ordinary abrasive powders, high-quality white aluminium oxide powder requires strict control of chemical composition, particle size distribution and contamination levels. These factors directly influence grinding efficiency, polishing quality and the final surface finish of processed materials.
YM Corundum provides different grades of white aluminium oxide powder, including fine powder, micro powder and customized particle sizes according to customer requirements. Our products are supplied to global industrial buyers involved in abrasive manufacturing, 도예, refractory materials and precision processing.
For customers who want to understand the technical characteristics of this material, our guide to white fused alumina properties explains purity, 경도, crystal structure and industrial performance in detail.
What Is White Aluminium Oxide Powder?
White aluminium oxide powder is a high-purity synthetic abrasive material mainly composed of alpha aluminum oxide (α-Al₂O₃). It is manufactured by melting calcined alumina in an electric arc furnace and then processing the fused blocks into different grain sizes and powder specifications.
According to the technical overview of aluminium oxide materials, aluminum oxide is one of the most widely used industrial ceramic materials because of its hardness, thermal stability and chemical resistance.
In abrasive applications, white aluminium oxide is valued because it combines:
- 높은 경도
- Sharp abrasive edges
- 낮은 철 오염
- Excellent thermal resistance
- Stable chemical performance
- Controlled particle distribution
Compared with brown fused alumina, white aluminium oxide generally provides higher purity and cleaner processing characteristics. This makes it suitable for applications where surface contamination needs to be minimized.
산업용 구매자를 위한, selecting the correct abrasive powder is not only about purchasing a certain grit size. The final performance depends on the relationship between material hardness, 입자 크기, processing method and application requirements.
