The invention relates to producing a silicate containing at least one type of silicium and oxygen consisting (1) in mixing silicium dioxide and/or silicium dioxide precursors with an aqueous solution, which comprises at least one type of R<SUB>1</SUB>R<SUB>2</SUB>R<SUB>3</SUB>R<SUB>4</SUB>N<SUP>+</SUP>compound containing a tetra-acryl ammonium compound and at least one type of base, wherein R<SUB>1</SUB> and R<SUB>2</SUB> represent methyl and, at the same time, R<SUB>3</SUB> and R<SUB>4</SUB> represent n-propyl; (2) in heating the colloidal solution thus obtained with a temperature greater than a boiling temperature at a selected colloidal solution pressure up to 180 °C at a normal pressure in such a way that at least one type of silicate-containing suspension is obtained. Said invention is characterised in that the silicium and oxygen-containing silicate is added in the form of a crystallisation-assisting agent.
