article description
The thermal properties of LaSrC0NiOceramics were analyzed. The photopyroelectric technique was used to measure the thermal conductivity and heat capacity. The results showed that these materials exhibit a metallic-type variation of thermal conductivity with temperature while no metal-insulator (M-I) transition was found to occur in any sample.
