Product Description
White Fused Alumina Introduction
White Fused Alumina (white corundum) is produced by the grinding & classification of selected Macro grain feed stock in an advanced milling and classifying facility.
This ensures an iron free product of narrow particle size distribution and high whiteness.
And White fused alumina is obtained by high-purity low- sodium alumina powder after high-temperature melting, cooling, crystallization, and crushing.
It is a particle with tightly controlled particle size distribution and consistent aopearance.
