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 o C. Both frameworks collapse
into amorphous intermediate products after heating between 600 and 650 o 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 o 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.
