Alumina Boats Description

Alumina boats have high thermal conductivity, compressive strength, and thermal shock resistance. Alumina Ceramics as a fine technical ceramic material is widely used in a lot of industries. High purity alumina has superb performances in electrical insulation, high chemical resistance, and low thermal expansion. High purity alumina materials are excellent 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. Alumina tubes are widely used as a protector for high-temperature thermal couples.
