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(M.sub.1/nXO.sub.2):yYO.sub.2:SiO.sub.2, 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.
