METHOD OF PREPARING COATED REFRACTORY WARE
Patent
·
OSTI ID:4231463
A method is presented for preparing a dense, refractory coating on a vessel adapted to the handling of molten metals such as uranium and plutonium. According to the invention, the inner surface of a heat stable container formed of a refractory metal of either niobium, molybdenum, tantalum, or tungsten is coated with molten thorium within 10 minutes so as to present alloying with the refractory metal and then exposed to a reactive atmosphere of nitrogen at a temperature of about 1750 deg for 30 minutes to form a refractory thorium nitride coating.
