Patent ID: 7470391

Claim:
A producing unit for continuously producing metal microparticles formed of a multicomponent alloy accompanied by the generation of a byproduct gas through an early reaction of the formation of the metal particles, comprising: a first mixing unit for continuously supplying and mixing at least a first solution and a second solution for conducting an early reaction and forming a reaction liquid containing metal microparticles; a second mixing unit for continuously supplying third solution to the reaction liquid and for mixing the third solution and the reaction liquid to introduce dissimilar metal atoms into the crystal lattices of the metal microparticles and to form a mixed solution; a pipe connecting the first mixing unit and the second mixing unit; and a gas-liquid separation unit installed in a midway position of the pipe, wherein the pipe is made so as to have enough length to finish the early reaction, continuously passes the reaction liquid to the second mixing unit from the first mixing unit, and continuously removes a byproduct gas generated as the early reaction proceeds.
