The thermal recovery processes in ion exchanged cobalt samples of zeolites were occurred at about 550K to adjust Brillouin zones, with the exception of Co4A sample in which optical phonons were generated and became free, whereas in the remaining samples, the acoustical phonons were quantized in Brillouin zones.
