molybdenum boat

Thermal vacuum evaporation (resistance evaporation) is a coating method used as part of the PVD process (Physical Vapor Deposition). The material that is to form the subsequent layer is heated in a vacuum chamber until it evaporates.The vapor formed by the material condenses on the substrate and forms the required layer. Because many coating materials react with water, nitrogen and oxygen, this process is performed in a high vacuum. The high temperatures that are required are generally produced using resistance heaters or, in some cases, induction heaters, electron beams or arcs. Evaporation boats are manufactured from refractory metals such as molybdenum, tungsten or tantalum to help them withstand these high temperatures as well as the chemical aggressions caused by the coating material.In the vacuum evaporation process resistant layers are produced, for example, from aluminum, silver, chromium, titanium nitride or silica. The result: Gleaming watches, flawless mirrors and top-quality electronic components. You can be assured of long service lives and a high level of dimensional accuracy: Thanks to our many years of experience, we are able to optimize the material and geometries of our evaporation boats to meet the precise requirements of your processes. We would be very happy toWe produce boats designed to hold the material for evaporation. These are manufactured from tungsten, molybdenum, molybdenum-lanthanum (ML), molybdenum-yttrium oxide (MY) or tantalum, offer a good level of electrical conductivity and possess low vapor pressures combined with a very high melting point. When powered on, our boats heat the material for evaporation. During this process, the low vapor pressures of our metals ensure that no tungsten, tantalum or molybdenum particles enter the vapor and penetrate the subsequent layer.
