Thermal diffusivity and heat capacity measurements of Li_2ZrO_3 and Li_2TiO_3 with the laser-flash method

摘要

Thermal diffusivity of 0.95Li_2ZrO_3 + 0.05ZrO_2(Li_2O/ZrO_2 = 0.95) was determined from 300 to 1200 K, and thermal diffusivity and heat capacity of 0.916Li_2TiO_3 + 0.017Li_4Ti_5O_(12)(Li_2O/TiO_2 = 0.95) were determined from 300 to 1100 K and 300 to 1000 K, respectively, by using the laser-flash method. Then, their thermal conductivities were calculated up to 1000 K using smoothed values of the thermal diffusivity and heat capacity.
