Aluminum oxide, commonly known as alumina, is a versatile and hard-wearing ceramic material that consists of aluminum and oxygen atoms. It exhibits exceptional hardness and is used in a wide array of applications, including as an abrasive material in sandpapers and grinding wheels due to its ability to cut and shape various surfaces. Additionally, aluminum oxide serves as an insulating material in electronics, a catalyst in chemical processes, and as a refractory material in high-temperature environments such as furnaces and crucibles. Its combination of hardness, high melting point, and electrical insulating properties makes aluminum oxide a crucial material in industries ranging from manufacturing to electronics.
Aluminum oxide
Aluminum oxide Brown aluminum oxide is electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown colour, high hardness and great toughness. The abrasives tools made of brown aluminum oxide are suitable for steel, malleable cast iron and hard bronze. It used for refractory aluminum oxide lining mixture, pouring materials castable, etc. White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, abrasive powder of finer grit size can also be used for precision casting and high-grade refractory.
