Description
Li2TiO3, one of the promising candidates for tritium breeding in a thermonuclear fusion reactor, has been investigated by X-ray diffraction at high temperatures. It was found that the crystal system of Li2TiO3 is monoclinic at 30-900 oC with a higher order structural phase transition at about 450 oC, showing agreement with dependence of thermal conductivity on temperature. This phase transition involved variation of the thermal expansion coefficient, which could also be observed by dilatometry
