| description | Data on thermally induced transformations of Mn exchanged zeolites LTA and
FAU topology are presented in this paper. Thermally induced phase
transformation of Mn-exchange zeolites are followed in the range from 700 to
1300°C. Both frameworks collapse into amorphous intermediate products after
heating between 600 and 650°C. Prolonged heating of the intermediate
product above 1100°C results directly in formation of a disorder
Mn-anorthiteLTA and Mn-anorthiteFAU. The parameter of unit cell of
Mn-anorthiteLTA and Mn-anorthiteFAU, in temperature range between 700 and
1300°C, was observed in space group C-1. The phase conversions in the
temperature range investigated were followed by thermal, X-ray powder
diffraction and FT-IR analyses |
