| Abstract: | A pulse method was used to measure the thermal conductivity, specific heat capacity C
p and thermal diffusivityξ of polycrystalline ZnIn2Se4 in the temperature range 300–600 K. The temperature dependence of λ, C
p and ξ demonstrated a light decrease for this material in the temperature range 300–600 K, indicating that there is not a
significant change in the structure in this temperature range; this was confirmed by DTA measurements. The results showed
that the mechanism of heat transfer is due mainly to phonons; the contributions of electrons and dipoles are very small.
