The melting point of Tungsten is 3410℃, Molybdenum is 2520 ℃, Tantalum is 3017℃. Therefore, these materials are often used tomake vessels for evaporation coating, such as evaporation boat, evaporation crucible, etc. In addition, Tungsten and Tantalum are also used as heating elements to provide the heat required for the  material evaporation.

Evaporation source, as a heating element required for evaporation and coating, can sometimes be made into a small heating chamber, which can adjust the evaporation rate by adjusting the temperature to complete the coating production with the evaporation process.
