FIELD: chemistry.
SUBSTANCE: invention relates to the field of obtaining pyrocarbon and carbide coatings in a fluidised bed (FB) of particles with a polyfractional composition, changing in the process of the coating precipitation, and can be used in nuclear and electronic equipment. A device for the coating precipitation in FB contains a chemical reactor and a system for the supply of fluidising gas in it. The chemical reactor is made in the form of a right parallelepiped with rounded edges and a rectangle-shaped base. One lateral face of the reactor has a square shape, another lateral face has a shape of a rectangle, whose area equals the area of the base. The ratio of areas of the lateral faces constitutes 1:(1.8-2), with the rectangular faces being provided with convexities in the places where diagonals cross.
EFFECT: increased stability of a totality of particles in the chemical reactor is provided which results in the prevention of a carryover of the particles, which the coating is applied on.
