Platelet Calcined aluminum oxide powder

Platelet Calcined aluminum oxide powder

Platelet calcined aluminum oxide powder, also known as tabulated alumina grinding powder. The name comes from the crystal shape of flat plates that look like platelets. The crystal form of platelet alumina is α- Al2O3 has high hardness and grinding performance. In the electronics industry, polishing and polishing require high surface precision. To ensure precise grinding effects and yield, abrasive materials with sharp crystal shapes can no longer meet the requirements. The surface of the abrasive particles of platelet alumina is flat and smooth. And the diameter-to-thickness ratio of the particles can be adjusted by adjusting the synthesis method. Grinding semiconductor chips or other microelectronic components is less prone to scratches. Thus, it greatly improves the yield of qualified chips. The production of platelet calcined alumina adopts a high-temperature calcined method to promote the lateral growth of crystals and form regular hexagonal powders with a tabulated structure. The suspension-treated aluminum oxide grinding powder of platelet shape gets a uniform particle size distribution. That ensures a fine grinding surface.

The features of Platelet Calcined aluminum oxide powder:

1. The Platelet Calcined aluminum oxide powder produced by Haixu Abrasives can achieve the grinding effect of imported sheet-like aluminum oxide powder compared to imported products.
2. The crystal form is flat without edges and corners, and during grinding, the abrasive particles produce a flat sliding effect between the workpiece, making it less prone to scratches.
3. High hardness and strong grinding force. Plate shape alumina has properties similar to corundum α- Al2O3 crystal phase, suitable for grinding and polishing of most materials.
4. Low magnetic content, high cleanliness, and high particle size consistency.
5. High melting point, high mechanical strength, and high grinding efficiency.
6. The particle size is controllable and can be obtained from 3 to 50 microns.
7. The flatness of the particles makes the flake alumina powder easy to disperse, making it suitable for making abrasives or grinding liquids.
8. It has corrosion resistance, strong chemical stability, and superior antioxidant performance, and will not react with liquid media in the grinding fluid.
9. Large specific surface area, surface activity and adhesion due to fused corundum.
10. Platelet calcined alumina is easy to disperse, and the powder is not easy to aggregate on the surface of the wafer, causing accumulation and affecting the polishing smoothness.

FAQ

A: Where is the original country of the aluminum oxide powder?

Q: The platelet calcined aluminum oxide powder is made in China.

A: Can this platelet alumina powder replace FUJIMI PWA 15?

Q: It can get the same grinding effect as FUJIMI PWA 15. The performance is about 80-90% of PWA15 or WCA15.

A: Is the platelet aluminum oxide made from Calcining or fusing process?

Q: It is made from a calcining process at about 1200 degrees. The sieving and water treatment processes are in the same production line of fused aluminum oxide powder.
