Abstract
The invention concerns a peroxosilicated, optionally phosphatized, disinfecting compound with scale preventive effect obtained by reacting an alkaline or alkaline-earth metasilicate with an active oxygen-releasing compound, for example potassium monopersulphate and/or oxygen peroxide, in inert medium. The compound can be stabilized with sodium hexametaphosphate. Copper and aluminium in salt form can be encapsulated or complexed with the metasilicate so that the resulting peroxosilicated compound can be used for its disinfecting, scale preventive, anticorrosive, flocculating and algicidal properties for more than three weeks.
