it is possible to obtain a solid material containing zeolite phase
such as zeolite X, zeolite A or sodalite. The presence of zeolite phase was confirmed by the measurement
of spectra in the middle infrared. In particular in pseudolattice range of the spectra, i.e. 800e400 cm1,
there are bands associated with the ring vibrations, which are characteristic for secondary building units
(SBU) occurred in zeolite structure. IR spectroscopy is also useful in the studies of resulting amorphous
phase structure.
