High wear resistance white fused alumina 220# for Tile Grout

Manufactured from high-purity fused alumina blocks, the product undergoes precise crushing, shaping and strict mesh classification to form uniform 220# angular particles. Its iron oxide content is controlled at an extremely low level, ensuring pure snow-white powder without black spots or colored impurities. Unlike traditional fillers such as calcium carbonate and quartz powder, this alumina boasts Mohs hardness 9, which greatly enhances the surface hardness of cured tile grout. Daily friction from shoe soles, furniture dragging and regular cleaning will not leave obvious scratches or wear marks, effectively solving the common problem of soft, easily worn inferior grout.

In mixing process, 220# white fused alumina features excellent fluidity and good compatibility with epoxy, polyurea and resin systems. It disperses evenly without agglomeration, sedimentation or stratification during automatic batching and stirring. The dense particle filling structure improves the compactness of grout, reducing water absorption and stain accumulation. It is resistant to acid, alkali and aging, suitable for high-humidity environments like kitchens, bathrooms and balconies, and will not turn yellow or black after long-term use.

This alumina filler maintains stable batch consistency with low moisture content, meeting mass production standards of tile grout factories. It works well for matte, bright and color sand grout formulas, upgrading the durability and surface texture of finished grout. For manufacturers pursuing high-quality, long-lasting tile joint products, 220# wear-resistant white fused alumina is the ideal reinforcing raw material.

DESCRIPTION-High wear resistance white fused alumina 220# for Tile Grout

White Fused Alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
