An enhancement of the O diffusivity in the grain boundaries of YSZ was reported to be more that three orders of magnitude greater than the diffusivity in single crystals. [Pg.412]

Gornyy and Al tovsky (1970), Spedding and Shiba (1972) determined the anisotropy of self-diffusion in single crystals of Y and Er, respectively. Selfdiffusion in Y seems to be strongly anisotropic to contrast to the results in Er (table 12.1). Further work, particularly in the hep phas es of the heavy rare earth metals, should elucidate this problem. [Pg.852]

Near-surface diffusion in single crystals and thin amorphous films was studied by means of charged-particle Rutherford back-scattering and ion microprobe techniques at 200 to 450C. It was found that the former results could be described by ... [Pg.9]

Bulk diffusion in single crystals was studied at 827 to 1192K. The diffusion coefficients were found to range from 1.2 x 10"1 to 1.1 x 10"Hcm2/s. The results could be described by ... [Pg.42]

By using p-n junction-depth and electrical conductivity measurements, a study was made of diffusion in single crystals. At 1250C, the diffusivity was equal to 3.3 x 10"12cm2/s and, at 1100 to 1250C, the results could be described by ... [Pg.78]

The serial sectioning method was used to study the diffusion of 124gb j to 0.005 to O.Olmm-thick itaxial films of p-type material. It was found that, for dislocation densities of 10 to lO /cm, the measured diffusivities agreed with those for Sb diffusion in single crystals. At 1250 to 1500K, the data could be described by ... [Pg.114]

Anodization etching and radioactive tracer analyses were used to study self-diffusion in single crystals which had various degrees of perfection and doping. The O content was equal to about 5 x lO /cm, and the dislocation densities were of the order of lOO/cm or less. For intrinsic material at 1100 to 1300C, it was found that ... [Pg.118]

A radioactive tracer and sectioning technique was used to study impurity diffusion, and the isotope effect for Li and Li diffusion, in single crystals. The data, for 200 to 400C, could be described by ... [Pg.137]

Nickel self-diffusion in single-crystals was measured as a function of temperature and O2 pressure at 1182 to 1762C and from 1 to 5 x 10" atm. In pure O2 and in pure... [Pg.231]

Tritium diffusion in single crystals of rutile was measured between 155 and 300C. The diffusivities were calculated from concentration profiles obtained from microdensitometer traces of autoradiographs generated by the P-decay of the tritium. The diffusivity was anisotropic, and was described by ... [Pg.259]
