The thermal conductivities of the LaPO_4/Al_2O_3 composites that were fabricated by spark plasma sintering (SPS) were determined. The results revealed that their thermal conductivities displayed nearly a slow decrease with increasing temperature from 25℃ to 800℃, having the classic I/T dependence. In addition, the conductivities of the composites decrease monotonously with increasing the LaPO_4 content because of the lower thermal conductivity of LaPO_4. The calculated conductivities of the composites using Maxwell equation match well the experimental values at both the end members of LaPO_4 and Al_2O_3 being the continuous phase, but showing a little deviation at intermediate composition.
