Using a dynamic electrical‐heating technique, we have measured the thermal conductivity and specific heat of NdP5O14, a high‐Nd‐concentration laser material. The measured values of the thermal‐conductivity tensor elements (in W/cm K) are Λa=2.10×10−2, Λb=9.66×10−3, and Λc=1.40×10−2. The specific heat is 0.141 cal/g K, in excellent agreement with the value of 0.139 cal/g K that we measured by differential scanning calorimetry.
