Description

Tungsten evaporation products refer to materials and components made from tungsten designed explicitly for use in thin-film deposition through evaporation. Thin-film deposition is a technique commonly employed in various industries, including electronics, optics, and materials science, to create thin layers of material on a substrate.

The main products include evaporation materials, evaporation sources of Tungsten Boats, and Tungsten Crucibles.

Here are some key aspects related to tungsten evaporation products:

  • Evaporation Sources:Tungsten is often used as the material for the evaporation source in physical vapor deposition (PVD) processes. Tungsten boats, coils, or filaments are heated to high temperatures within a vacuum chamber, causing the tungsten to evaporate and deposit as a thin film on the substrate.
  • Purity: The purity of tungsten used in evaporation products is crucial to ensure high-quality thin films. High-purity tungsten helps in achieving precise and reproducible results in thin-film deposition applications.
  • Applications:Tungsten evaporation is widely used in the production of microelectronic devices, semiconductors, sensors, and optical coatings. Tungsten films exhibit good adhesion, wear resistance, and high melting points, making them suitable for various demanding applications.
  • Tungsten Crucibles: In addition to evaporation sources, tungsten crucibles are also used in the process. Crucibles made of tungsten are resistant to high temperatures and are employed to contain the material that will be evaporated.
  • Customized Products:We offer a range of tungsten evaporation products, including crucibles, boats, filaments, and other specialized components. These products may be customized based on the specific requirements of the thin-film deposition process.
