  • Method for manufacturing fine composite particles, apparatus for manufacturing fine composite particles, and fine composite particles
    Patent number: 8017235
    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.
    Type: Grant
    Filed: August 17, 2004
    Date of Patent: September 13, 2011
    Assignee: National Institute of Advanced Industrial Science and Technology
    Inventors: Hiroyuki Nakamura, Masato Uehara, Hongzhi Wang, Hideaki Maeda, Masaya Miyazaki, Yoshiko Yamaguchi, Kenichi Yamashita, Hazime Shimizu, Xyanying Li
