The tritium breeders for a fusion reactor, Li2O, LiAlO2, and Li4SiO4, are compared on a thermochemical basis in respect to their response to protium purging. Two oxygen activity levels, established by H2O:H2 ratios of 100: 1 and 1:100 are considered at the temperatures 900 and 1300K. In terms of tritium release (all gaseous forms), LiAlO2 is better than Li2O and this in turn better than Li4SiO4. At 900K, Li2O and LiAlO2 release more tritium than at 1300K. Li4SiO4 releases more tritium at 1300K than at 900K.
