Zusammenfassung:	The invention relates to a method for producing fine-grained solids and/or for depositing layers of poorly soluble compounds from a liquid phase. The aim of the invention is to develop a simple, cost-effective method for producing fine-grained solids and/or layers of poorly soluble compounds, according to which the formation of the solid matter is coupled to a chemical reaction that can be controlled over time, whereby the starting materials can be mixed together without the occurrence of a spontaneous reaction and the characteristics of the forming solids and solid layers can be specifically influenced by the choice of reaction conditions. According to the invention, to achieve this aim, solutions containing metallic ions, sols or suspensions in the alkaline range are reacted with one or more esters. Said reaction uses esters, which during saponification produce an acid that does not form a precipitation product with the metallic ions, or uses esters of carbonic acid or silicic acid.
