Abstract: The present invention addresses the aims and problems of providing a method of producing silicon fine particles and a method of controlling the particle size of silicon fine particles, which enable silicon fine particles having a uniform particle size to be efficiently produced. The present invention is characterized in that silicon particles are immersed in an etching solution, a light having greater energy than the band gap energy of the silicon particles is irradiated onto the silicon particles immersed in the etching solution, and thereby silicon fine particles with a smaller particle size than the silicon particles are produced while controlling the particle size.

Abstract: A powder having good oxidation resistance and controlled electrical properties is obtained by dispersing minute particulates in a matrix phase to form composite particles. The minute particulates may be distributed uniformly, or non-uniformly such that the particulates are dense near the particle surface and sparse near the centre or vice versa. The minute particulates have a moderate conductivity of from 10 to 10 Scm , and the matrix phase has a low conductivity of up to 1/10 of that of the particulates. The powder can be dispersed in an insulating oily medium to form an electrorheological fluid.
