Thermally induced phase transformations of Pb-exchange LTA and FAU zeolites were from ambient temperature to 1300 degrees C. Both frameworks collapse into amorphous intermediate products after heating between 600 and 650 degrees C. Prolonged heating of the intermediate product over 1100 degrees C results in the formation of disordered Pb-feldspar(LTA) [a = 8.414 (4) angstrom, b = 13.048 (4) angstrom, c = 7.169 (4) angstrom, beta = 115.35 degrees (3)] and Pb-feldspar(FAU) [a = 8.422 (4) angstrom, b = 13.054 (4) angstrom, c = 7.173 (4) angstrom, beta = 115.37 degrees (3)] phases. The phase conversions within the investigated temperature range were followed by thermal (DTA, TGA, and DSC), XRPD, and Raman methods. (C) 2014 Elsevier Inc. All rights reserved.
