Dense composites consisting of copper and ZrW₂O₈ (ZrWMoO₈) with negative thermal expansion (NTE) properties were fabricated at low temperature by using spark plasma sintering (SPS). X-ray diffraction (XRD) analyses suggested that the Cu-ZrW₂O₈ and Cu-ZrWMoO₈ composites were thermally stable at 773 K and 673 K. The coefficient of thermal expansion (CTE), as measured by a thermodynamic analyzer, could be varied from negative to positive by increasing the volume fraction of copper. The Cu-ZrW₂O₈ composite showed a change in the slope of the thermal expansion curve that was due to a phase transition, whereas the Cu-ZrWMoO₈ composite showed no such change. The thermal conductivity of Cu-ZrW₂O₈ increased with the copper content, varying from 157 [W/mK] (Cu: 50 vol%) to 300 [W/mK] (Cu: 100 vol%).
