Abstract

A method for the production of spherical particles. The starting material for the particles and organic substances are used to form a liquid aqueous mix from which drops are formed. The starting material is introduced into an aqueous solution in the form of a fine powder. The solution contains condensable or curable organic substances. As the starting material a non-metal, metalloid or a compound of one of these is used.
