White fused alumina powder #1000
White fused alumina powder is made from high-purity alumina melted in an electric arc furnace and finelycrushed into micro-sized particles. The powder is characterized by high hardness, sharp crystal edges, andexcellent stability, ensuring superior grinding and polishing performance. lts low impurity content and highmelting point enable consistent behavior under high temperatures and chemical exposure. With precise particle size control and exceptional purity, white fused alumina powder is widely used in precisionpolishing, lapping, and fine surface finishing. lt is an ideal material for optical lenses, semiconductors, ceramiccomponents, and metal surface treatment where uniformity and cleanliness are critical.
