Thermal Properties of Calcium Phosphate for Biomedical Use
- Conference date: 27–31 July 2009
- Location: México City, (México)
The possibilities that offer the photo thermal techniques to determine the thermal properties widely have been demonstrated [1,2]. From these techniques, photo acoustic and photo pyrelectric has turned out to be very useful in studies of biological materials, which frequently present many difficulties due to a high dispersion to the light and structures that vary with the depth. In this work we used the photo acoustic technique in the configuration of open cell and the photo pyrelectric technique, to determine the thermal properties of natural and synthetic calcium phosphate for biomedical use. We report the determination of the values obtained for the diffusivity (a), effusivity (ε), thermal conductivity (k) and heat capacity (ρc), of 6 synthetic calcium phosphate samples and 5 natural calcium phosphate samples. The values obtained for the thermal properties of synthetic calcium phosphates turn out to be 82% similar to the values obtained for calcium phosphates of natural origin. This behavior allows us to obtained calcium phosphates in our laboratory like osseous substitutes with thermal properties similar to the calcium phosphates of natural origin.
