Glass rock is currently a common jewelry accessory, widely used in clothing, evening dresses, shoes, hats, handbags, headwear, woolen textiles, bead embroidery, lighting, handicrafts, etc. Its composition is inert silica. White corundum is made of high-quality aluminum oxide powder as raw material, and white corundum is refined and crystallized by electric melting. It has high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. The hardness of white corundum is slightly higher than that of brown corundum, with slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, and high temperature and thermal stability. The abrasive tool is made of white corundum grain sand, which is suitable for grinding fine-grained abrasives such as high-carbon steel, high-speed steel and stainless steel. White corundum can also be used for precision casting and advanced refractory materials. Brown corundum is made of bauxite, anthracite, and iron filings as the main raw materials. It is smelted at high temperature in an electric arc furnace. It has a brown color, good toughness, microhardness 1800-2200Kg/mm2, bulk density ≥3.85g/cm3, and resistance to High temperature and refractoriness up to 1850℃, it can be used as refractory material and abrasive.
