1. A method for synthesizing zeolites comprising the step of heating a reaction mixture under crystallization conditions for a sufficient period to form a disordered zeolite having both CHA and AEI topologies, wherein the reaction mixture comprises:
a. at least one source of aluminum,
b. at least one source of silicon,
c. a source of alkaline or alkaline-earth cations,
d. a structure direction agent containing at least one source of quaternary ammonium cations and at least one source of alkyl-substituted piperidinium cations in a molar ratio of about 0.20 to about 1.4, and
e. is essentially free of halides.
