Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina is high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metalizing.
• Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles, and insulators.
• Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
• Used as the protector for high-temperature thermal couples.
• Used as a material for the chemical industry due to its high corrosion resistance.
