Abstract

Particles are coated by tumbling the particles in a drum into which powder grains which have been previously treated with a binder are introduced, and softening the binder by contacting the grains with a solvent for the binder as the grains enter the drum. The coated particles may be formed into compacts by pressing and heating to set the binder. The particles may be nuclear fuel particles e.g. carbides of nuclear fuel metals, which may be precoated with a fission product retaining layer of pyrolytic carbon, the powder grains being a carbonaceous material such as graphite. In the embodiment of the invention, a batch of nuclear fuel particles pre-coated with pyrolytic carbon was placed in a rotary drum. A supply of graphitised grains of calcined petroleum coke treated with a phenol-formaldehyde resin and a supply of solvent methylated spirit were mounted above the drum, suitable feed pipes being arranged to communicate the supply of grains and solvent with the interior of the drum so that the grain and a mist of the solvent contacted one another. The coated particles were then heated in a furnace in vacuum, divided into batches which were formed into compacts using an electrically heated die.
