Tungsten Evaporation Boats:
Tungsten evaporation boats are small, boat-shaped containers made from high-purity tungsten metal. They are typically used in high-temperature vacuum environments, such as thermal evaporation systems. The boat shape allows for easy loading and positioning of the material to be evaporated. Tungsten is chosen as the material for these boats due to its high melting point, excellent thermal conductivity, and low vapor pressure at high temperatures. These properties ensure efficient and controlled evaporation of the material being deposited. Tungsten evaporation boats are commonly used in applications such as thin film deposition for semiconductor manufacturing, optical coatings, and surface engineering.
