White corundum is refined from industrial alumina powder using modern unique processing technology. Main component: The content of aluminum oxide (Al2O3) is over 98%, and it contains a small amount of iron oxide, silicon oxide, etc. It is white and is melted in an electric arc at temperatures above 2000 degrees, then cooled and crushed, shaped, magnetically separated to remove iron, and screened into various particle sizes. It has a dense texture, high hardness, and sharp angular particles.

White corundum has a hardness slightly higher than brown corundum, with slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, and good high-temperature thermal stability. Tools made from white corundum sand are suitable for grinding high carbon steel, high-speed steel, and stainless steel, among other fine-grained abrasives. White corundum segment sand can also be used for precision casting and high-grade refractory materials.

White corundum abrasive is a high-performance corundum material, with its main component being α-Al2O3 crystal phase, possessing a series of excellent characteristics such as high hardness, great strength, good wear resistance, high temperature resistance, and corrosion resistance. The following are the main characteristics of white corundum abrasive:

1. High hardness: The hardness of white corundum reaches above 9, which is much higher than that of ordinary abrasives, allowing it to effectively grind hard metal materials such as ceramics and glass. The high hardness also gives white corundum good wear resistance during the grinding process, extending its service life.

2. Good wear resistance: White corundum abrasive has very high wear resistance, allowing it to maintain a long service life during high-speed grinding. This characteristic makes white corundum widely used in mechanical manufacturing, steel, aviation, aerospace, and other fields.

3. High-temperature stability: White corundum abrasive can maintain good stability at high temperatures without losing its grinding effectiveness due to high temperatures. Therefore, it is suitable for high-temperature grinding fields, meeting the needs for processing in high-temperature environments.

4. Strong corrosion resistance: White corundum abrasive has good corrosion resistance, allowing it to be used in some corrosive environments such as strong acids and strong bases. This characteristic gives white corundum a broad application prospect in the chemical industry, petrochemical industry, and other sectors.

5. Uniform particle size: The particle size distribution of white corundum abrasive is uniform, with a particle size range generally from 1 to 50 microns. This feature allows white corundum to exert a significant grinding effect in different processing processes, while also meeting the requirements of various processing techniques. By controlling the particle size through screening, different processing precision requirements can be achieved.

6. Not easy to break: White corundum abrasive has high toughness and anti-fracture performance, which can reduce debris and damage during the grinding process, improving service life.

7. Good insulation: White corundum abrasive also has good insulation properties, making it applicable in the manufacturing of electronic components and insulating materials.
