Abstract

The present invention relates to a process for the production of a zeolitic material having a framework structure comprising YO2, wherein said process comprises: (1) preparing a mixture comprising one or more tetravalent elements Y in elemental form, one or more organic hydroxide salts, and one or more protic solvents; (2) reacting the mixture obtained in step (1) for converting at least part of the one or more tetravalent elements Y into an oxidic form thereof containing one or more Y—O single bonds and/or one or more Y═O double bonds; and (3) crystallizing a zeolitic material from the mixture obtained in step (2).
