Abstract

Method of manufacturing the silica nanopowders with fungicidal properties, consists in that the silica gel is obtained by sol-gel method from the reaction mixture containing tetraalkoxysilane and aliphatic alcohol, in the presence of ammonium compound, and thereafter the thermodegradable copper(II) salt a compound from the group of carbofunctional alkoxysilanes, and then, after evaporation of solvents the dry residue is heated at the decomposition temperature of copper(II) salt.
