METHOD OF PRODUCING NANOPOWDER AND DEVICE TO THIS END Russian patent published in 2012 - IPC B22F9/16 B82B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to production of powder materials, in particular, nanopowders. Material to be evaporated is placed in evaporation chamber to be evaporated therein by laser radiation and condensed in gas flow. Heat reactor is arranged at evaporation chamber outlet to maintain preset temperature of particles condensed in gas flow to allow synthesis of compound and formation of particle crystalline structure in the part of particles through reactor. Geometrical sizes of heat reactor are selected proceeding from the following condition: (S_r ×l_r)/Q_g≥τ_ft, where S_r is heating zone cross-section, l_r is heating zone length, Q_g is gas flow rate through reactor, τ_ft is characteristic time of solid-phase reactions in particles in synthesis of the compound.

EFFECT: nanopowders with completed diffusion and solid-phase reactions, preset crystalline structure.
