3.Good refractory materials,
Goodsale alumina powder wholesale for polishing
White Fused Alumina (WFA,WA)
White fusedalumina (WFA, WA) is produced by fusing and extracting fromcrystallization with high quality alumina oxide powder as rawmaterials
It isfeatured by high purity, self-sharpening, and acid-alkali andcorrosion resistance, temperature tolerance.etc.
Usage:
Abrasives(mainly), abrasive tools, abrasive polishing materials, blastingcoated materials, grinding wheels,
Refractories,exactitude foundry, steel-making, super refractory materials,etc.
Also makingchemical accelerant carrier, special ceramic , etc.
