●Alumina Ceramic is a hard material ( mohs hardness 9 ), so it is a challenging to obtain a smooth surface by traditional mechanical polishing techniques.

●This Kona water-based alumina slurry has been designed for polishing alumina ceramic components, such as Alumina Ceramic substrates, Alumina Ceramic Seal Ring and so on.

●Our alumina polishing powders are also available for ceramic polishing, as well as alumina slurry.

●We also have Polishing Slurry base on silica colloidal provides a highly smooth surface for ceramic final polishing.
