Abstract: A process for the calcination of a zeolitic material, wherein the process contains the steps of (i) providing a zeolitic material containing YO2 and optionally further containing X2O3 in its framework structure in the form of a powder and/or of a suspension of the zeolitic material in a liquid, wherein Y stands for a tetravalent element and X stands for a trivalent element; (ii) atomization of the powder and/or of the suspension of the zeolitic material provided in (i) in a gas stream for obtaining an aerosol; and (iii) calcination of the aerosol obtained in (ii) for obtaining a calcined powder, a zeolitic material obtained by the above process, and its use as a molecular sieve, as an adsorbent, for ion-exchange, as a catalyst, and/or as a catalyst support.
