Kinetics of carbon deposition in a fluidized bed

Abstract

Abstract Rate data have been obtained for the deposition of carbon films from methane and acetylene in fluidized beds of alumina, uranium dioxide, uranium monocarbide, uranium dicarbide, and a solid solution of uranium‐thorium dicarbide powders. These carbon films have been shown to provide excellent protection for the powdered fertile material against attack by hot concentrated nitric‐acid solutions. The coated uranium‐thorium dicarbide particles were also shown to be stable in humid air.
