Abstract: The present invention relates to a process for the preparation of a zeolitic material having a CHA-type framework structure comprising YO2 and X2O3, wherein said process comprises the steps of: (1) providing a mixture comprising one or more sources for YO2, one or more sources for X2O3, one or more tetraalkylammonium cation R1R2R3R4N+-containing compounds, and one or more tetraalkylammonium cation R5R6R7R8N+-containing compounds as structure directing agent; (2) crystallizing the mixture obtained in step (1) for obtaining a zeolitic material having a CHA-type framework structure; wherein Y is a tetravalent element and X is a trivalent element, wherein R1, R2, R3, R4, R5, R6, and R7 independently from one another stand for alkyl, and wherein R8 stands for cycloalkyl, as well as to zeolitic materials which may be obtained according to the inventive process and to their use.
