Abstract
A resistance heated evaporator includes a body of graphite having a generally rectangular geometry with opposite ends each of which has four sides. A coating of pyrolytic boron nitride covers substantially the entire surface of three of the sides at each end so as to form a channel which provides structural support at each end. At least one side at each end remains open for electrical contact to a power supply.
Claims4
A resistant heated flash evaporator for flash evaporating metal in contact with the evaporator comprising:
- a body having opposite ends each of which has four sides and a coating of pyrolytic boron nitride substantially covering the entire surface of three of said sides to form a three sided channel at each opposite end leaving at least one side at each opposite end open for electrical contact to a power supply whereby said channel forms a structural support at each opposite end.
