We examined the compatibility of lithium titanite (Li2TiO 3, tritium breeding materials) fused crystals with nickel (Ni) foils by Rutherford backscattering spectroscopy (RBS) after heat-treatments at 673 K, 773 K and 873 K for 600 min in vacuum (10-6 Pa). An inter diffusion of Ni and titanium (Ti) atoms at 773 K followed a diffusion of a small amount of Ni atoms into the surface of Li2TiO3 at 673 K. At 873 K, Ti and oxygen (O) atoms reached the front surface of the Ni foil and Ni atoms migrated into the Li2TiO3 crystal. In addition, we estimated the diffusion constants at 873 K for Ti and O in Ni.
