Application
Mainly used for manufacturing high-precision cutting and grinding tools, mechanical components, hard alloy additives, optoelectronic devices, semiconductor manufacturing materials, grinding and polishing materials, mortar and coating additives, etc. Due to its high hardness and wear resistance, plate-shaped corundum has a wide range of applications in various fields, including steel, casting, ceramics, and other industries

Chemical Analysis

The chemical composition of plate-like corundum mainly includes aluminum oxide (Al ₂ O3), with a content usually above 99%, and also contains small amounts of impurities such as silicon dioxide (SiO ₂), calcium oxide (CaO), iron oxide (Fe ₂ O3), and sodium oxide (Na ₂ O). The specific chemical composition parameters are: AL ₂ O3 ≥ 99.2%, SiO ₂ ≤ 0.05%, CaO ≤ 0.04%, Fe ₂ O3 ≤ 0.05%, Na ₂ O ≤ 0.40%.
