Abstract
Lithium titanate (Li 2TiO 3) is one of the most promising candidates among the proposed solid breeder materials in fusion reactors because of its chemical satiability. Addition of H 2 to inert sweep gas has been proposed for enhancing the release of bred tritium from breeder material. However, the mass of Li 2TiO 3 has been found to decrease with time in the hydrogen atmosphere. In order to control the mass change at the time of high-temperature use, development of Li 2TiO 3 which has excess Li 2O is needed. Li 2TiO 3 (L100) and Li 2.1TiO 3.05 (L105) were prepared by solid-state reaction at 1273 K of Li 2CO 3 and TiO 2 powders. In thermogravimetry, the masses of samples L100 and L105 were found to decrease with time in a hydrogen atmosphere, then to increase after a change of the atmosphere from hydrogen to oxygen. Sample L105 has fewer oxygen defects than L100. An atmosphere-controlled high-temperature mass spectrometer has provided the vapor pressure data for L100 and L105, under the conditions of D 2 atmospheres. Sample L105 has a higher partial pressure of total Li-containing species than L100 above 1093 K.
