Alumina Boat Description

Alumina boat 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 Boat Applications

Aluminum oxide boats can be used in the following applications:

 High alumina combustions boats are ideal for chemists, metallurgists, and other scientists involved in high-temperature work demanding contamination-free results.
 Used with refractory metals such as molybdenum, platinum, rhodium, tungsten, tantalum, and iridium
 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 a protector for high-temperature thermal couples.
 Used as a material for the chemical industry due to its high corrosion resistance.
