Tabular corundum is a material composed of alumina crystals, and its properties mainly include the following aspects:
1. High hardness: The hardness of tabular corundum has reached 9 on the Mohs scale, which makes it have high anti-wear performance and can be used for a long time in high temperature and high pressure environment without easy wear.
2. Heat resistance: It can be used for a long time in a high-temperature environment of more than 1000 meters, and has good thermal conductivity to ensure that the temperature of the material surface is uniform.
3. Low coefficient of thermal expansion: close to metal materials, which makes tabular corundum not easy to produce stress and deformation when the temperature changes, and maintains the stability and reliability of the material.
4. Corrosion resistance: It can be used for a long time in strong acids, strong alkalis and other corrosive media without damage, which makes tabular corundum have a wide range of application prospects in some special industrial fields.
5. Good mechanical properties: tabular corundum has high strength and rigidity, can withstand large mechanical loads, and at the same time, it also has good fracture toughness and is not easy to break and break.
6. Electrical insulation: Tabular corundum is an excellent electrical insulating material, which makes it widely used in the electronics industry and high-voltage equipment.
Tabular corundum is also a kind of sintered corundum with high purity and good crystallinity, with a well-developed -Al2O3 crystal structure, and the content of Al2O3 is more than 99%. It also has the characteristics of good volume stability and small re-burning shrinkage. In the production process, tabular corundum does not need to add any additives, ensuring its purity and stable performance.
