Plate-shaped alumina polishing powder is made of high-quality industrial alumina powder as raw material, and is processed by a special production process. The crystal shape of the produced alumina polishing powder is hexagonal plate-shaped, so it is called plate-shaped alumina or flake alumina.
The alumina purity of the flat alumina is more than 99%, and it has the characteristics of heat resistance, acid and alkali corrosion resistance, and high hardness. Different from the traditional abrasive spherical particles, the bottom surface of the flat alumina is flat, and the particles adhere to the surface of the workpiece during grinding, resulting in a sliding grinding effect, which avoids the scratches on the surface of the workpiece by the sharp corners of the particles. During grinding, the grinding pressure is evenly distributed on the surface of the particles, the particles are not easily broken, and the wear resistance is improved, thereby improving the grinding efficiency and surface finish.

Features of Alumina Flake Powder
The application of flat alumina in the semiconductor material industry can reduce the grinding time, greatly improve the grinding efficiency, reduce the loss of the grinding machine, save labor and grinding costs, and improve the grinding qualification rate.
The grinding efficiency of the glass bulb of the picture tube is improved by 3-5 times;
The qualified product rate has increased by 10-15, and the qualified product rate of semiconductor silicon wafers has reached more than 99;
The grinding consumption is 40% less than that of ordinary alumina polishing powder.
The role of flat alumina powder
-Functional coating film: The plate-like alumina with superior performance has no agglomeration phenomenon, and has good adhesion. It is easy to combine with other functional micropowders to prepare various promising new functional coating materials. Alumina coatings for capillaries can significantly improve their reversal electroosmotic flow performance and selectivity and stability for target analysis; functional coatings for stealth aircraft can absorb radio waves to prevent them from being detected by radar.
Inorganic fillers: Plate alumina is an indispensable filler in industrial production. It is used in functional ceramics, plastics and rubber products to increase hardness and stiffness, and to adjust shrinkage and thermal expansion coefficient.
Abrasive polishing liquid: Compared with the conventional nano-alumina, the flat and smooth flake surface is not easy to scratch the object to be ground, and the qualified product rate of the product can be increased by 10% to 15%. It has become a new favorite in the high-precision microelectronics industry, gem processing industry and metal ceramics industry.
