Additionally, tungsten has a low vapor pressure, which means it has minimal vapor contamination, making it suitable for high-purity applications. Tungsten boats have a long lifespan and can be used repeatedly without significant deterioration.

What Are Thermal Evaporation Sources?

Thermal evaporation sources are devices used in thermal evaporation systems to deposit thin films onto substrates. They work by heating a material (evaporant) to high temperatures, causing it to evaporate and then condense onto a substrate, forming a thin film.

How Are High-purity Graphite Crucibles Made?

High-purity graphite crucibles are typically manufactured through a process called isostatic pressing. In this method, graphite powder is placed in a rubber mold, and then subjected to high pressure from all directions. This pressure compacts the graphite particles into a dense and uniform crucible shape. The crucible is then heated to a high temperature to remove any impurities and improve its purity.

What Are The Main Types Of Thermal Evaporation Sources?

The main types of thermal evaporation sources include resistive evaporation sources, electron-beam evaporation sources, and flash evaporation sources. Each type uses different methods to heat the evaporant, such as resistive heating, electron beam heating, or direct contact with a hot surface.

What Are The Common Applications Of High-purity Graphite Crucibles?

High-purity graphite crucibles have a wide range of applications in industries such as metallurgy, foundries, and laboratories.
