1. Special material melting and high temperature synthesis
Tantalum crucibles can withstand extremely high temperatures and are suitable for melting high melting point metals (such as tantalum, tungsten, iridium) and special alloys. It is also suitable for the synthesis of high temperature ceramic materials and superhard alloys, which usually require very pure materials and are prepared under extreme conditions.
2. Preparation of fine chemicals
Due to its excellent corrosion resistance, tantalum crucibles can be safely used in the refining process of corrosive chemicals containing strong acids and alkalis such as halogens and aqua regia to ensure the purity of chemicals and the smooth progress of reactions.
3. Electronic material manufacturing
In the semiconductor industry, tantalum crucibles are used for the refining of semiconductor materials such as polysilicon and gallium arsenide to ensure the high purity of materials. These materials are the basis for manufacturing electronic components such as chips and solar panels.
4. Vacuum electronic devices
The properties of tantalum make it an ideal material for cathodes or conductive parts in vacuum electronic devices such as electron tubes, X-ray tubes, and vacuum tubes, because tantalum still maintains good performance in a vacuum.
