Description

Alumina Crucible Description

Alumina crucible is a ceramic product with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in crucible, tube, and thermocouple sheath form. Alumina is high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metallizing. Alumina crucibles can be used under high temperature and do not contaminate most molten metals.

Alumina Crucible Applications

Alumina Al2O3 crucibles are used in the following applications:

• 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 the protector for high-temperature thermal couples.
• Used as a material for the chemical industry due to its high corrosion resistance.

Alumina Crucible Packaging

Our Alumina crucibles are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
