    Abstract: The present invention relates to a process for the preparation of a zeolitic material comprising SiO 2 and X 2 O 3 in its framework structure, wherein Y stands for a tetravalent element and X stands for a trivalent element, wherein said process comprises:
    (i) preparing a mixture comprising one or more sources of SiO 2 , one or more sources of X 2 O 3 , and H 2 O, wherein the one or more sources of SiO 2 comprises one or more cyclic compounds according to formula (I):

             [-(MR'R")-O]n     (I)

    wherein M stands for one or more elements selected from the group consisting of Si, Al, and Ti, including combinations of two or three thereof,
    wherein n is an integer comprised in the range of from 3 to 12, and
    wherein independently from one another, R' and R" stand for H, OMc, alkyl, alkoxy, or siloxy,
    wherein Mc stands for a cationic moiety; and

    (ii) grinding and/or mixing the mixture prepared in (i);
    (iii) heating the mixture obtained in (ii) for crystallizing a zeolitic material comprising SiO 2 and X 2 O 3 in its framework structure from the mixture. Furthermore, the present invention relates to a zeolitic material comprising SiO 2 and X 2 O 3 in its framework structure obtainable and/or obtained according to the inventive process, wherein X stands for a trivalent element, as well as to the use of the zeolitic material obtainable and/or obtained according to the inventive process.
