Product Description
White Fused Alumina WFA powder
white corundum powder WFA powder for Ceramic membrane tube is a white abrasive made from industrial alumina powder (Al2O3) with a content of over 98% and a small amount of iron oxide and silicon oxide. It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness and sharp in shape.
· High hardness and dense particles. Single particle roundness is good.
· The color is pure white, no impurities, to ensure the wear-resistant layer or wear-resistant paper color and transparency.
· Uniform distribution of particle size, single-particle shape consistent, with a small amount of wear - resistant effect.
· Excellent Chemical stability with high acid-alkali resistance, high temperature stability.
· white fused alumina oxide powder JIS 8000 grit from HAIXU Abrasive is produced strictly according to FEPA and JIS standard, all products are tested and qualified before shipment.
· Low electrical conductivity; moderately-high thermal conductivity; good refractoriness and resistance to molten metals.
