The flake alumina HPA provided by our company is kind of Alpha phase alumina powder. Its crystal is thin and smooth. Its Mohs hardness is 9 and smelting point is 2030℃. It can work for very long term at 1200℃ with stable chemical and physical performance. The powder has following features:

1. Flake Shape

2. High strength
3. High hardness
4. High temperature resistance
5. High thermal conductivity
6. Stable chemical properties
7. Dielectric property
8. Smooth surface
9. Nanometer thickness
10. Thickness diameter ratio between 80 and 100.

It’s typical sheet shape. The product is applied in pearlescent pigment industry, making the product present “Shining Crystal Effect”.

The phase of single crystal flake alumina is alpha corundum phase, which has many excellent properties such as acid and alkali resistance, high temperature resistance, high mechanical strength, high hardness, high thermal conductivity and high resistivity. In addition to pearlescent industry, it can also be used in special coatings, cosmetics, automotive topcoat, ink, filler and abrasives. In addition, it can also be used as catalyst carrier, heat exchange medium, technical ceramics, etc. it has potential application prospects in the fields of microelectronics industry, special metal protective coating, military stealth materials, etc.
