Thermal diffusivity and conductivity of Li2ZrO3 using the modulated electron beam technique
Abstract
Thermal diffusivity and thermal conductivity of three Li2ZrO3 specimens with two different density values, 82.6 and 87% theoretical density, have been measured between 350 and 900°C. The modulated electron beam thermal diffusivity method was used. Heating the specimens above some 850°C but below 900°C results in a reversible increase in both the diffusivity and the conductivity. When heating to higher temperatures generally still higher increases are noticed but measurements become rapidly unstable and irreversible.
