Abstract
The photopyroelectric technique is suitable for study pasty substance of processing stone residues in Cachoeiro de Itapemirim’s region, Espírito Santo. Due to the non-destructive character, application in transparent or opaque materials and possibility of sample’s thickness or modulation radiating frequency scanning for thermal properties detection. This technique can be configured in several setups. In this work, standard (SPPE) one were used for determination sample’s thermal diffusivity, and inverse (IPPE) one, that allows determination sample’s thermal effusiveness. By these thermal parameters values, it’s possible get the sample’s thermal conductivity. The objective of this work is to analyze the different values of thermal diffusivity and effusivity for different kind stones, hard and softy classified, in order to determine thermal parameters, as a thermal conductivity, and to promote an observation of the sensitivity of the technique.
