High Temperature Tungsten W Crucible Description
Prepare high-purity tungsten powder for compression molding or isostatic pressing, sinter the pre-sintered green body at high temperature, and then carry out mechanical processing such as turning, grinding, drilling, etc. Finally, surface treatment and comprehensive quality inspection will be carried out.
Features
- High melting point, excellent dimensional stability at high temperatures, and strong resistance to deformation.
- Good chemical stability and corrosion resistance ensure high purity during melting.
- Excellent electrical and thermal conductivity allows for uniform heat distribution, enhancing melting efficiency.
- High strength, hardness, good machinability, and long service life.
Application
- Metal smelting: used for high-temperature smelting of rare earth metals and refractory metals.
- Semiconductor processing: used to refine high-purity single-crystal silicon to meet the strict requirements of semiconductor devices for silicon.
- Electron beam melting: used to uniformly heat and melt metal raw materials,
- Optical instruments: used for the growth of laser crystals such as YAG and sapphire for application in optical windows.
- Powder metallurgy: used for sintering containers of metal powders to ensure the stability of subsequent processing.
