Abstract: The present invention relates to a process for the preparation of a zeolitic material comprising YO2 in its framework structure, wherein Y stands for a tetravalent element, wherein said process comprises the steps of: (1) providing a mixture comprising one or more sources for YO2, one or more fluoride containing compounds, and one or more structure directing agents; (2) crystallizing the mixture obtained in step (1) for obtaining a zeolitic material comprising YO2 in its framework structure; wherein the mixture provided in step (1) and crystallized in step (2) contains 35 wt.-% or less of H2O based on 100 wt.-% of YO2 contained in the mixture provided in step (1) and crystallized in step (2), as well as to a zeolitic material comprising YO2 in its framework structure obtainable and/or obtained according to said process, and to a zeolitic material per se comprising SiO2 in its framework structure, wherein in the 29Si MAS NMR spectrum of the as-synthesized zeolitic material the ratio of the total integration value of the peaks associated to Q3 signals to the total integration value of the peaks associated to Q4 signals is in the range of from 0:100 to 20:80, including the use of the aforementioned zeolitic materials.
