Brown molten aluminum oxide is produced by melting high-quality bauxite in an electric arc furnace at high temperatures. It is of compressive strength, high toughness, good self-sharpening, lower coefficient of expansion, no rusty stain, good hydrophilicity, high cleaning, heat resistance and chemical stability, etc.
Suitable for many different applications such as: grinding wheels, sandpaper, blasting media, metal preparation, polishing, polishing and grinding. Due to its thermal properties, it can also be used for refractory applications.
