Abstract
The equilibrium vapor pressures in the system of Li2ZrO3-D-2 were measured by means of atmosphere controlled high temperature mass spectrometry. The e ffect of D-2 on vaporization of lithium containing species was investigated quantitatively. The sum of the partial pressures of lithium containing spe cies was estimated to be approximately 0.002 Pa at 1000 It under the condit ion of 0.1% hydrogen addition into the helium purge gas. The standard entha lpies of the reactions in this system were calculated from the experimental data, which suggested a possibility of non-stoichiometric composition in t he surface region of Li2ZrO3.
