摘要：

The thermal diffusivity (alpha) of single-phase (Ca1-xMgx)Zr4(PO4)6, or CMZP, ceramic with x=0.1 and x=0.4 was investigated in terms of porosity and temperature. The thermal diffusivity exhibits a lower temperature dependence at higher pore content and is roughly independent of temperature above 300-degrees-C In the same thermal environment, CMZP with x=0.4 shows lower values of thermal diffusivity compared with that having x=0.1. The phonon mean free path (L) is calculated to be 2.2 angstrom for x=0.1 and 1.7 angstrom for x=0.4.
