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.
