Descripción : | We present a microstructural study and thermal diffusivity measurements at room
temperature in two different sections of bull dense bone, bull bone and commercial
hydroxyapatite, the last two in powder form. A comparison was realised between these
measured values and those obtained from metallic samples frequently used in implants, as
high purity titanium and 316L stainless steel. Our results show that the porosity and its
orientation in the bone are two important factors for the heat flux through the bone. On the
other hand, we obtained that the hydroxyapatite, in compact powder form, presents a thermal
diffusivity value close to those obtained for the samples of bone which gives a good thermal
agreement between these materials. Finally, it was obtained at one order of magnitude
difference between the thermal diffusivity values of metallic samples and those corresponding
values to bone and hydroxyapatite being this difference greater in titanium than in stainless
steel. Research article of proceedings of IV Mexican Symposium on Medical Physics Instituto Politecnico Nacional |
