The present invention relates to a process for the preparation of crystalline molecular sieves, in particular large pore zeolites, said process consisting in bringing into contact active sources of one or more oxides chosen from the group comprising oxides of monovalent elements, oxides of bivalent elements, oxides of trivalent elements, oxides of tetravalent elements, and oxides of pentavalent elements, with an organocationic matrixing agent derived from a 3,7-diazabicyclo [3.3.1] nonane. |
