Chemical Vapor Deposition (CVD) Tungsten Crucible

The tungsten crucible produced by CVD has some characteristics such as high density up to 98.5% of theoretical density, high purity of 99.9999%, the particular microstructure of columnar crystal or multilayer columnar crystal, etc.

Tungsten crucible is widely used in technologies for growing monocrystals from molten corundum, it is also used in electronics and technologies for thermal vaporization - deposition of various substances. It is an important part of the high-temperature furnace that causes its high melting point. Our tungsten crucibles feature exceptional thickness transition, smooth surface, high purity, and strong creep resistance.

Applications of Tungsten Crucible

1. Semiconductor Manufacturing: Used for melting and holding high-purity materials such as silicon, gallium arsenide, and germanium during the crystal growth process in semiconductor fabrication.

2. Metallurgy: Employed in producing high-temperature alloys and metals such as titanium, steel, and superalloys, where tungsten crucibles provide a stable and inert environment for melting and casting processes.

3. Chemical Processing: Utilized for containing and heating highly corrosive chemicals and molten salts in chemical synthesis, refining, and purification processes due to tungsten's resistance to corrosion and high temperatures.

4. Glass Manufacturing: Found in the production of specialty glasses and optical fibers, where tungsten crucibles provide a stable and contamination-free environment for melting and shaping glass materials.

5. Thin Film Deposition: Used in physical vapor deposition (PVD) and chemical vapor deposition (CVD) processes for producing thin films and coatings on substrates in semiconductor, optical, and aerospace industries.

6. Laboratory Research: Employed in laboratory settings for high-temperature experiments, synthesis of materials, and chemical reactions where inert and stable containers are required.
