Molybdenum Boats in Vacuum Coater
Molybdenum boats are used as evaporation part in vacuum coater, or in evaporator vessel, which is an essential part. Due to properties of molybdenum boats, molybdenum boats are coordinated with vacuum coater and evaporator vessel to make related machine into working.
Picture on the right side is a general view of the vacuum coater. The large cylindrical object on the left is an ion bombardier for cleaning and degassing. The substrate is at the top under the foil. The foil is there to minimize deposition on the bell jar. Evaporation was done thermally using a molybdenum boat.

The finished Molybdenum boats are made by rolled high temperature Molybdenum plate with the excellent characters of strength and high temperature resistance. It's orderly and tidily profiled and well welded in order to ensure the boat having a best lifetime under the condition of high temperature and stress.
Molybdenum sheets are widely used in making electric internal furnace, heating-insulated screen, electronics, electronic-vacuum illumination, light sources industry, thermo screen, etc.
Molybdenum rods have theproperties of high melting point, good thermal conductivity and low thermal expansion. At high temperature, they can resist oxidation and have high strength without any distortion during the procession, etc.
Pure molybdenum can be presented in many types. Molybdenum bar is one popular product made of molybdenum. Therefore, molybdenum bar shares the properties of molybdenum, which are high melting point, good thermal conductivity and low thermal expansion. At high temperature, they can resist oxidation and have high strength without any distortion during the procession, etc.
