METHOD OF PRODUCING METALLIC NANOPOWDERS BY DECOMPOSITION OF METAL CARBONYL IN USING INDUCTION PLASMA BURNER Russian patent published in 2012 - IPC B22F9/30 B82Y30/00

Abstract RU 2457925 C2

FIELD: process engineering.

SUBSTANCE: invention relates to making metallic nanopowders by feeding metal carbonyl into induction plasma burner. Metal carbonyl is decomposed there inside to produce nano-sized metal particles, in fact, of spherical shape to cool down said particles by gas for fast cooling in reactor arranged on plasma burner outlet side and collect them. Metal carbonyl is selected from the group consisting of nickel carbonyl, iron carbonyl, copper carbonyl, cobalt carbonyl, chromium carbonyl, molybdenum carbonyl, tungsten carbonyl, and ruthenium carbonyl.

EFFECT: higher efficiency of producing particles with improved spherical morphology and degree of crystallinity.
