Abstract

A partly hydrolyzed gelled polysiloxane mass is contacted with a solution of dopant metal compounds which diffuse therein under thermally controlled condition; alternatively, a partly hydrolyzed gelled polysiloxane mass containing distributed therein dopant metal compounds is contacted with a solvent into which said dopant metal compounds will partly diffuse under thermally controlled conditions.
