摘要：
The thermodynamic calculations of dissociation of LiAlO2 and LiGaO2 as function of temperature and oxygen pressure are presented. It has been found that LiGaO2 evaporates congruently at the melting point under the oxygen pressure equal to 1&middot10-5 atm. LiAlO2 evaporates incongruently, the equilibrium oxygen partial pressure at the melting point is equal to 9.6&middot10-5 atm and the partial pressure of Li and Al oxides decrease with increasing of oxygen pressure.
