Claim:
1. A process for the preparation of a zeolitic material having a CHA framework structure wherein said process comprises (1) providing a mixture comprising (2) crystallizing the mixture provided in (1); wherein Y is a tetravalent element, and X is a trivalent element, and wherein the molar ratio of ammonium cation having the formula (I) to Y in the mixture provided in (1) and crystallized in (2) is equal to or greater than 0.25; wherein the zeolitic material comprises YO wherein the zeolitic material displays a Y:X molar ratio in the range of from 1.5 to 10.5, wherein the zeolitic material optionally further comprises Z wherein the zeolitic material then displays a Y:nX:pZ molar ratio, the value for the ratio (1+2p):(n−p) is in the range of from 1 to 5.5.
