Alumina Crucible

1. Basic characteristics of alumina crucible

High purity: Alumina crucibles are usually made of high-purity alumina (Al₂O₃), with a purity of more than 99%, which ensures its stability and corrosion resistance in high temperature environments.

High temperature resistance: Alumina crucibles can remain stable for a long time at high temperatures, and have a wide range of operating temperatures. They can usually be used for a long time at 1650°C, and the short-term use temperature can even reach 1800°C.

Corrosion resistance: Alumina crucibles have good corrosion resistance to a variety of chemical substances and can maintain the stability of their physical and chemical properties in harsh chemical environments.

High strength: Alumina crucibles have excellent mechanical strength and can withstand various stresses generated at high temperatures, and are not easy to deform or break.

2. Application advantages

Improve production efficiency: The high high temperature resistance and corrosion resistance of alumina crucibles enable them to remain stable for a long time in harsh working environments, thereby improving the production efficiency of vacuum aluminum-plated metal films.

Reducing production costs: Alumina crucibles have a long service life and a high reuse rate, which reduces production costs and improves the economic benefits of enterprises.

Environmentally friendly and sustainable: Alumina crucible is an environmentally friendly material. It does not produce harmful substances during its production and use, which meets the requirements of sustainable development.
