Abstract

The invention relates to a method for producing particulate composite materials. According to the method, solid inorganic or organic particle agglomerates or particle aggregates that are provided in a dry state, particularly in powder form, are first reduced in size in the gas phase or in a gaseous carrier medium in the presence of organic matrix particles by applying energy. The obtained comminuted particles are dispersed into the organic matrix particles, especially embedded thereinto and/or attached thereto. The composite materials produced in said manner can be used in many different ways and are suitable in particular for use in a large variety of plastic materials, coating materials, paints, and lacquers, especially coating powders, to modify properties during use in the corresponding products and similar.
