Application

Ceramics Industry
— Glaze Grinding: Uniform roundness ensures higher gloss and smoother surface finish of the final products.
— Body Material Milling: Hardness well-matched with feldspar and quartz, improving grinding efficiency by approximately 20%.

Glass Industry
— Suitable for soda ash grinding, with no iron residue contamination.

Chemical Industry
— Resistant to hydrofluoric acid corrosion, serving as an alternative to synthetic grinding pebbles.
