Applications of Tungsten Boat:
1)As a special and effective boat vessel, tungsten boat is widely used in electron-beam spraying as well as the sintering and annealing process in vacuum coating industries;
2)Tungsten boats are used for vacuum evaporation of materials in granular or pellet form;
3)They can also be used to evaporate small lengths of wire or to evaporate materials which would not properly "wet" the surface of an evaporation filament;
4)Tungsten evaporation boats are ideal for use in small evaporation systems for experimental and prototype work, such as bell jars.
