Alumina Boats, Al2O3 Ceramic Boat


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

The above chart just demonstrates the typical properties of common alumina ceramic we use to produce our alumina parts. Please notice that the properties of customized alumina parts vary due to different processing. Edgetech Industries, Advanced Ceramics Division provides alumina products according to your specified instructions, or do the best to meet requirements.


Alumina Boats Application


-Spare parts for pan-semiconductor equipment (manufacturing equipment such as LCD and LED)


-Wear parts

-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, the 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, and vacuum packing is also engaged for some of the parts.
