Abstract
Anisotropy in the thermal properties in alpha SiO2 single crystals SC cut m ode 1 and mode 2 was investigated using the photoacosutic (PA) frequency tr ansmission technique. The PA amplitude and phase diagrams were measured and numerically analyzed. The obtained results for the thermal diffusivity for SC mod1 was 0.34x10(-5) m(2)/s while it was 0.40x10(-5) m(2)/s for mode 2. The differences in PA spectra for both SC cuts were larger compared with m uch smaller differences which were observed using infrared reflectivity spe ctra.
