AB  - Polarized far- and mid-infrared reflectance spectra were measured at room temperature for the new mineral species jarandolite, CaB3O4(OH)(3), for the two principal directions. Thirty three vibration modes for (E) over right arrow parallel to(c) over right arrowc and 32 for (E) over right arrow perpendicular to(c) over right arrow were observed and analysed numerically. Symmetry analysis predicts 41 (E) over right arrow parallel to(c) over right arrow and 40 (E) over right arrow perpendicular to(c) over right arrow vibration modes that include lattice and O-H modes. Mode assignment was made based on the structure of jarandolite. The values of the mode frequencies (omega(TO)), the damping factors (gamma) and the oscillator strength (S) of each oscillator were obtained by fitting to a Lorentz model.

AB  - Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered up to 1200 degrees C with a heating rate of 5 degrees C/min. X-ray diffraction analysis of obtained powders and sintered samples was performed in order to investigate changes of the phase composition. The microstructure of sintered samples was examined by scanning electron microscopy. The photoacoustic phase and amplitude spectra of sintered samples were measured as a function of the laser beam modulating frequency using a transmission detection configuration. Fitting of experimental data enabled determination of photoacoustic properties including thermal diffusiviiy. Based on the results obtained a correlation between thermal diffusivity and experimental conditions as well the samples microstructure characteristics was discussed.
