다이아몬드와 화이트 커런덤, 둘 다 단단한 재료이긴 하지만, 구성에 상당한 차이가 있습니다, 속성 및 응용 프로그램, which make them useful and advantageous in different fields and scenarios.
1. Composition and manufacturing process:
Adamantine: Adamantine is a generic term and does not have a single composition. It can contain a variety of materials such as silicon carbide, white corundum, black corundum and so on. Among them, silicon carbide is generated due to the reaction between silica in clay and carbon under high temperature conditions. And the manufacturing process of corundum may vary depending on its composition.
화이트 커런덤: White corundum is mainly composed of aluminium oxide (Al2O3), which is more than 98%. In addition to this, white corundum also contains small amounts of iron oxide and silicon oxide, which gives it a white colour. White corundum is made from industrial alumina powder, which is melted at high temperature by electric arc and then cooled.
2. Physical Properties:
Adamantine: Adamantine has high hardness, second only to diamond. 게다가, it is anti-abrasive and chemically stable. Due to its physical properties, emery can be found in a wide range of particle sizes and shapes to suit different applications.
화이트 커런덤: White corundum also has high hardness, but its hardness is slightly lower than that of diamond. It has good abrasion resistance and chemical stability, which allows white corundum to remain stable at high temperatures, high pressures and in corrosive environments.

3. Application fields:
Diamond: due to its high hardness and anti-abrasive properties, diamond is widely used in grinding, cutting, polishing and other processes. 게다가, emery can also be used for surface treatment, such as sandblasting cleaning and enhancing coating adhesion.
화이트 커런덤: White corundum is mainly used in the manufacture of refractory materials, such as refractory bricks, refractory coatings and high temperature ceramics. 게다가, white corundum is used in the manufacture of ceramics, resin cemented abrasives and grinding and polishing tools. White corundum also has applications in the electronics, electrical and high temperature industries.
4. Use and Selection:
The choice of corundum or white corundum depends largely on the specific application needs and requirements. If high hardness and abrasion resistance are required, as well as the need to be suitable for a wide range of grain sizes and shapes, then corundum may be a good choice. Whereas if it is required for the manufacture of refractory materials or for use in areas such as grinding and polishing tools, then white corundum may be more appropriate.
In summary, although both emery and white corundum are hard materials, they differ significantly in their composition, 속성 및 응용 프로그램. Understanding these differences helps us to choose the right material for different application scenarios so as to meet specific needs and requirements.
