Abstract
The atmosphere controlled high temperature mass spectrometer has provided vapor pressure data for lithium-based oxide ceramics under condition of low pressure hydrogen introduction. The measured vaporization behaviors under hydrogen addition of Li4SiO4, LiAlO2, Li2TiO3, and Li2ZrO3 are summarized. From the experimental data, sum of the partial pressures of lithium containing species was estimated for each oxide. It was pointed out that hydrogen addition seemed to cause the formation of a nonstoichiometric layer at the surfaces of Li4SiO4 and Li2ZrO3. Work function measurement was employed as a new method for investigation of such oxygen deficient layers. The results of the work function measurements showed the formation of an oxygen deficient surface layer for Li4SiO4 and for Li2ZrO3, whereas such was not the case for Li2TiO3.
