Abstract
In the present invention, the fine particle composite process is carried out with the step of reacting fine core particles and a raw material for coating layer by mixing them and continuously supplying a resulting mixture into a micro flow path. The micro flow path is specified to 1-4000 in Reynolds number. With this arrangement, the present invention ensures, in a technology using a reactor having a micro flow path, accurate control of reaction condition, uniformity of coating amount distribution, easy layer formation, and successive production of fine composite particles.
