The invention relates to a microporous crystalline zeolite material which, in the calcined state and in the absence of defects in the crystalline lattice thereof, manifested by the presence of silanols, has empirical formula x(MXO):yYO:SiO, in which M is selected from among H+, at least one inorganic cation with charge +n and a mixture of both; X is at least one chemical element in oxidation state +3; Y is at least one chemical element in oxidation state +4, which is different from Si, x has a value of between 0 and 0.2 inclusive, and y has a value of between 0 and 0.1 inclusive. In addition, as it is synthesised, and in the calcined state, the material has a characteristic X-ray diffraction pattern known as ITQ-32. The invention also relates to the method of preparing said material and to the use thereof.
