Alumina Boats

Alumina ceramic is the most common technical material and a relatively traditional ceramic. High purity alumina has excellent performances in electrical insulation, high chemical resistance and low thermal expansion. Alumina Boats are used to make parts for CVD, ion implants, photolithography, and semiconductor.

-General machinery, hydraulic components

-Used as injector tubes, gas nozzles, and insulators.

-High temperature situations & a protector for high-temperature thermal couples.

Packing of Alumina Boats

As a ceramic material, Alumina Boat is quite fragile in a lot of cases. Our Alumina Ceramics are carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used, vacuum packing is also engaged for some of the parts.
