Method for Coating Actinide Particles.

PATENT3175922

Publication Date	1965
Personal Author	Blocher, J. M.; Browning, M. F.
Page Count	0
Abstract	The refractory coating is for nuclear reactor fuel or blanket particles. The coating may be alumina, zirconia and yttria. The thermal expansion characteristics are modified by treatment with minor amounts of chromia. A vertical reactor of the fluidized bed type is utilized in the process. The actinide oxide particles are treated with hydrogen containing the vapors of chromyl and aluminum, zirconium, or yttrium chloride. Water is introduced during the process to hydrolyze the vapor.
Keywords	Coatings Reactor fuels Actinide series Uranium compounds Dioxides Particles Oxides Aluminum compounds Zirconium compounds Yttrium compounds Chromium compounds Preparation Chlorides Vapors Hydrogen Hydrolysis Patents Ceramic coatings Refractory coatings Aluminum oxides Chromic oxide Fluidized beds Uraneous oxide Yttrium oxide Zirconium oxides
