  • Lateral flash evaporator
    Patent number: 5671322
    Abstract: A resistant heated flash evaporator including a body of any desired geometry having two opposite open sides, a cavity which forms a continuous open area extending from each of the two opposite sides and at least one metal evaporating surface facing the open area for evaporating metal laterally through the opposite sides of the cavity. The body is preferably composed of graphite and has a coating of pyrolyric boron nitride extending over a substantial portion of the body and over the metal evaporating surface formed by the cavity.
