Crucible Alumina

Advantages of Alumina Ceramic

1. The operating temperature of Alumina crucibles is relatively high, generally able to withstand high temperatures of around 1600-1800 ℃.

2. Alumina crucibles have excellent resistance to many chemicals at high temperatures.

3. Alumina crucibles can maintain good performance in environments with significant temperature changes.

4. Under high temperature conditions, Alumina crucibles still have sufficient mechanical strength.

5. High quality Alumina crucibles have high purity, especially for experiments or production processes that require extremely high purity.

Applications of Alumina Ceramic

1. Alumina Crucible are widely used in the smelting and refining of metals.

2. Alumina Crucible are used for the production and processing of ceramic and glass materials.

3. Alumina Crucible are used for high-temperature chemical reactions.

4. Use an Alumina Crucible to test the thermal and chemical properties of the material.
