The invention relates to a process for the synthesis of zeolites, which comprises the following steps: a) provision of a silicon source; b) provision of an aluminium source; c) optionally provision of at least one template; d) mixing of the silicon source, the aluminium source and the optional template to produce a synthesis gel; e) milling of the synthesis gel; f) treatment of the milled synthesis gel under hydrothermal conditions to produce crystalline zeolite, and also zeolites which can be obtained by this process. The products obtained by the process can be used as catalysts or catalyst supports.
