Vacuum deposition - Wikipedia

Vacuum deposition is a family of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface. These processes operate at pressures well below atmospheric pressure (i.e., vacuum).The deposited layers can range from a thickness of one atom up to millimeters, forming freestanding structures.

Conductive Ceramic Evaporation Boats for Vacuum Web Coating

Jan 16, 2019 · Evaporation boats temperature too low will result in following. Aluminum wire will melt slowly and the molten aluminum will accumulate in cavity. This can lead to overflow of molten aluminum. This molten aluminum will spread over vacuum chamber and evaporation zone making it very dirty and can generate more impurities in coating.
