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.
