Abstract

PURPOSE:To obtain the fine powder comprising fine particles having wide use as an industrial stock material by enclosing a substance to be enclosed in a shell comprising an aggregated material of ultrafine particles with a definite diameter or less. CONSTITUTION:From a shell comprising an aggregated material of an ultrafine particulate substance (X) with a diameter of 0.5mu or less and a substance (Y) enclosed in said shell, a fine powder comprising fine particles is constituted. By changing combination of the shell constituting substance (X) and the substance (Y) to be enclosed in the shell, the obtained powder has wide use as an industrial stock mateial with various properties such as a pigment, an additive for an org. high molecular substance, a catalyst or the like.
