introduced and related results on the confinement effects on materials and solid–liquid phase transition were reviewed [ 1 ]. In the second part, the application of thermoporometry to obtain poresizedistribution (PSD) and various information about the pore
transform IR spectrometer (PERKIN-ELMER SYSTEM 2000 FTIR) was used to record IR spectra of the samples in KBr pressed pellets in the range of wavenumbers 400–4000 cm −1 .
The specific surface area value and poresizedistributions were determined
