Abstract
An evaporation method is described for the deposition of various materials that comprise a plurality of elements, such as metal alloys, ceramics and certain inorganic-metallic compounds. The method involves the evaporation of a material comprising a plurality of elements through a molten pool of another material. The material which is to be evaporated is placed in a suitable evaporation means under the material which is to be used to form the molten pool. By applying heat sufficient to melt both materials, the material to be evaporated is transported through the molten pool of the other material. The materials are selected so that the material to be evaporated is preferentially evaporated with respect to the other material. This method produces a vapor stream and condensates that have compositions which closely resemble the compositions of the material from which they were deposited. Further, the condensate may be collected using the method of this invention at high rates on the order of 0.50 mil/minute, or more.
