Abstract

The lattice parameter, thermal conductivity and electrical resistivity in off-stoichiometric ZrCx compounds were investigated and compared with previous research results. The change in the lattice constant as a function of carbon content in the present study was clearly different compared to results from previous studies. In the present study, the lattice constant decreased with the decrease in carbon content. In contrast, the lattice constant exhibited a maximum value at x = 0.8 in the previous studies. Moreover, the lattice constants obtained in this study were smaller than that of the previous studies at the same carbon contents. The changes in the thermal and electric properties as a function of carbon content and temperature exhibited the same trends in the present and previous studies. However, the values of the thermal conductivity at the same carbon content were different. The values in the present study were higher than those of the previous studies.
