Aluminium Oxide Crucibles Description
Aluminium oxide crucibles are ceramic products that exhibit high thermal conductivity, compressive strength and tolerance to temperature fluctuations. They display low thermal expansion, which makes them suitable for use in oven components such as crucibles, tubes and thermocouple sheaths. Aluminium oxide is hard and wear-resistant; it is used for manufacturing ball valves, piston pumps and deep-drawing tools. Furthermore, the material may be joined with metals and other ceramic materials by brazing and metallising. Aluminium oxide crucibles can be used at high temperatures and do not contaminate most molten metals.

Applications of Aluminium Oxide Crucibles
- Components for CVD, ion implantation, photolithography and semiconductor parts are manufactured using these products.
- They are used for injector tubes, gas nozzles and insulators in traditional industry.
- They serve as materials for industrial furnaces.
- They protect high-temperature thermocouple assemblies.
- They are employed in the chemical industry, given that they exhibit high resistance to corrosion.
Packaging of Aluminium Oxide Crucibles
Our aluminium oxide crucibles are handled with care to prevent damage during storage and transport, thereby preserving their original quality.
