Title: RESISTANCE OF CERAMIC FUEL-PARTICLE COATINGS TO REACTIONS WITH OXYGEN AND GRAPHITE
Abstract: The compatibtlity of coated particles with various matrix materials and environments was studied using metallugraphic and x-ray techniques. Al/sub 2/O/ sub 3/-coated UO/sub 2/ particles were resistant to oxidation for several thousand hours at temperatures to 1100 deg C and BeO-coated UO/sub 2/ particles to temperatures of 1000 deg C. In flowing argon, berylliagraphite mixtures formed the most stable oxide-graphite combination, followed by mixtures of graphite with alumina, magnesia, and zirconia. The results indicated beryllia-graphite mixtures to be compartible for 10000 hr at temperatures > 140O deg C, alumina- graphite to 1350 deg C, magnesia-graphite to 950 to 1000 deg C, and zircoria- graphite to 900 to 1000 deg C.
