Can tungsten be evaporated?

Yes, tungsten can be evaporated, but due to its high melting point of 3,422 °C (6,192 °F), extremely high temperatures are required. The evaporation of tungsten is usually achieved in a vacuum environment using techniques such as thermal evaporation or electron beam evaporation. In these processes, tungsten is heated to its evaporation point, causing it to transition from a solid to a vapor phase. This vapor can then condense onto a substrate to form a thin film or coating. However, due to the extreme conditions required, specialized equipment is required to perform the evaporation effectively.

What temperature does tungsten evaporate at?

Tungsten evaporates at extremely high temperatures, typically around 5,500 °C (9,932 °F) in a vacuum environment. This temperature is significantly higher than its melting point, which is around 3,422 °C (6,192 °F). The exact evaporation temperature can vary depending on the ambient pressure; in a vacuum, tungsten evaporates at a lower temperature than under atmospheric conditions. However, achieving and maintaining such high temperatures requires specialized equipment and techniques, such as electron beam evaporation or thermal evaporation in a vacuum chamber.
