PROCESS FOR THE PRODUCTION OF PARTICLES OR POWDERS

摘要

In a novel process for the production of parti- cles or powders, a substance or mixture of substances to be treated is provided in a pressure vessel. A compress- ible fluid is dissolved under pressure in the substance or mixture of substances provided, and the resulting solution is then decompressed so that particles form during the decompression. The particles which have formed are removed from the stream of decompressed compressible fluid.
