COMPARISON OF A FLUIDIZED-BED AND AN AGITATED-TROUGH CHEMICAL REACTOR FOR PRODUCING Th02 FROM Th(NO3)4

摘要

The continuous conversion of Th(NO3)4, solution to form 100- to 500-μ -dia ThO2 particles was tested in "both a fluidized bed and an agitated trough, Neither method was feasible for producing dense high-strength Th02 spheres. Instead of depositing uniform oxide layers on the hot surface of the bed particles, the Th(NO3)4 decomposed to form loosely-bound ThO2 agglomerates.
