The integrated diffusion coefficient of the phases and the tracer diffusion coefficients of the species are determined in the Nb-Si system by the diffusion couple technique. The diffusion rate of Si is found to be faster than that of Nb in both the NbSi 2 and Nb 5 Si 3 phases. The possible atomic me
According to the phase diagram of lithium niobate (LN) a decomposition of congruently melting LN with segregation of a niobium rich phase LiNb 3 O 8 (L3N) has been observed. It occurs at the surface and at defects within the LN crystals at temperatures significantly higher than 300 C. L3N crystals g
