    In the vacuum evaporation device, the most common type of evaporation heating device is the resistance evaporation device. The resistive material for heating is required to have a high use temperature, a low vapor pressure at a high temperature, no chemical reaction with the substance to be evaporated, no gassing or other contamination, and suitable electric resistance. This results in the resistance heating materials used in practice being generally refractory metals such as W, Mo, Ta, and the like. 

    One of the problems to be considered in selecting a heating device is the possibility of a chemical reaction between the evaporated material and the heating material. Many substances react chemically with refractory metals. In this case, consider using a boat coated with a layer of Al2O3 to prevent it. In addition, it is also necessary to prevent the material from splashing due to the deflation process of the heated substance. 

   The tungsten boat is formed by stamping a molybdenum sheet with a thickness of 0.1-0.5. The molybdenum boat plays the role of bearing and heating in the resistive evaporation device. We can design the mold according to the drawings provided by the customer and produce the finished molybdenum boat. 

    Please tell us the following dimensions of the tungsten boat you need, we will quote you.
