High-temperature calcined flake alumina polishing powder 5um 6um

High-Temperature Calcined Platelet Alumina Polishing Powder 5um 6um

PRODUCT/Product: Platelet Calcined Aluminum Oxide / Platelet Alumina

DESCRIPTION/Product Introduction:

Platelet calcined alumina powder, also known as tabulated aluminum oxide grinding powder. It is named after its particle crystal structure being in the shape of scales/flat plates. The crystal form of flake alumina is α-Al2O3, which has high hardness and grinding performance. In the electronics industry, polishing and grinding 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 flake/flat alumina is flat and smooth, and the diameter-to-thickness ratio of the particles can be adjusted by modifying the synthesis method. Grinding semiconductor chips or other microelectronic components is less prone to scratches, greatly improving the yield of qualified chips. The production of platelet calcined alumina adopts a high-temperature calcination method to promote lateral crystal growth and form regular hexagonal powders with a tabulated structure. The suspension-treated aluminum oxide grinding powder of platelet shape achieves a uniform particle size distribution, ensuring a fine grinding surface.

Platelet alumina, also known as flat-plate alumina, is named for its scale/plate-like particle crystal structure. The crystal form of platelet alumina is α-Al2O3, which exhibits high hardness and grinding performance. In the electronics industry, polishing and grinding demand high surface precision. To achieve fine grinding results and high yield, abrasive materials with sharp crystal shapes are no longer sufficient. The abrasive particles of platelet/flat alumina have a smooth and flat surface, and the particle diameter-to-thickness ratio can be adjusted by altering the synthesis method. When grinding semiconductor wafers or other microelectronic components, it is less likely to cause scratches, significantly increasing the yield of qualified chips. The production of platelet alumina employs a high-temperature sintering method to promote lateral crystal growth, forming regular hexagonal powders with a platelet structure. The washed and classified platelet alumina has a highly concentrated particle size distribution, contributing to consistent grinding surface quality.
