The main phase ZrV2O7 material, doped with zirconia and vanadium (V) oxide, was synthesized by solid state reaction and sol-gel methods. X-ray power diffraction patterns show that it is cubic structure. Thermal mechanic analysis measurements present a zero-thermal expansion of this material above 150℃. As well the heat capacity dependent on temperature, determined by differential scanning calorimetry, keeps in constant almost in the same temperature range. The relation between unusual thermal expansion and abnormal heat capacity is discussed with quantum mechanics.
