Premium Polishing Coarse Powder - High Purity Alumina Grinding Material

Product Description

 

Product Description

High purity alumina for polishing

 

Using the new green production process developed by ourselves, the purity of 4N-5N and the primary crystal 50-500nm are produced
High purity alumina for CMP precision polishing can provide customized products with different primary crystal size, morphology, specific surface, particle size and crystal type according to customer requirements.
Features
It adopts the method of air flow grinding, the physical and chemical indexes of the powder are relatively stable, and it has the characteristics of wear resistance and high temperature resistance, and will not change easily. At the same time, it can use closely developed crystal microstructure for engineering design, providing from large and coarse particles to finer agglomerated crystal clusters, to eliminate the rough or fine surface in the final product.

Apply

Polishing of optical lenses, rare and precious metals, ceramic components, car paint, sapphire and other single crystals
