FIELD: process engineering.
SUBSTANCE: invention relates to plasma chemical synthesis using transformer plasmatron to produce high-quality nanopowders of diverse substances. In compliance with this method, initial stock is fed in liquid or vaporous state, or gaseous state in induction discharge or in plasma jet. Plasma chemical reaction is performed at 1.01×105 Pa and higher, induction discharge frequency of 100-400 kHz and temperature of up to 10000 °C in atmosphere of reducing or oxidising gas. Produced powder is tempered and extracted from reaction zone. Proposed device comprises initial stock feed system, transformer plasmatron, nanopowders tempering system, water-cooled chamber, bag filter and nanopowders collector, all being interconnected.
EFFECT: high-quality nanopowders, efficiency, simple design, safe use.
