Lithium titanate (Li2TiO3) has attracted the attention of many researchers because of good tritium recovery at low temperature, chemical stability, low tritium inventory, etc. In this work, the effects of TiO2doping of Li2TiO3on the resistance to the environmental attack in air and hydrogen reduction under Ar+0.1%H2flow were examined. Based on the results, the TiO2doping (from 3.7 to 30 wt%) was found to improve the resistance to the environmental attack for very long exposure times in air at room temperature. The hydrogen reaction rates of Li2TiO3and Li4Ti5O12were almost similar up to 800°C and that of Li4Ti5O12was higher in the temperature range from 800 to 950°C. © 2003 Elsevier B.V.
