PROCESS FOR PRODUCING FINE PARTICLES AND THE FINE PARTICLES

摘要

This invention provides a process for producing fine particles, which can produce monodisperse fine particles, is free from clogging of a product by virtue of self-dischargeability, does not require a high pressure, and is also high in productivity. A fluid containing at least one raw material for fine particles dissolved therein is introduced into between treatment faces which are provided opposite to each other so that they come close to each other and are separable from each other and at least one of which is rotatable against the other treatment face to form a thin-film fluid. Fine particles are precipitated by cooling or heating the thin-film fluid to change the saturated solubility.
