Photoacoustic characterization of natural mineral pyrite (FeS2)
A single p-type crystal of the mineral, pyrite (FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic (PA) amplitude and phase spectra were measured using a specially ...
Thermal diffusivity of sintered 12CaO×7AI2O3
The thermal diffusivity and free carrier diffusion coefficient of 12CaO×7 Al2O3 (C12A7) sintered for different times in air or hydrogen followed by treatment with UV light were determined from photoacoustic phase and ...
