摘要：
The diffusion of titanium in TiO2-SiO2 glasses with up to 7 mol% TiO2 was investigated by annealing doped layers on the inner surface of quartz glass tubes between 1700 and 200 degrees C and measuring radial doping profiles via X-ray microprobe analysis and refractive index profiling subsequent to the tube collapse. By comparison with calculated profiles diffusion coefficients were able to be determined and fitted with an Arrhenius function. Both the preexponential D-0 = 10((0.56 + 0.51c)) cm(2)center dot s(-1) and the activation energy E = ( 473 + 11.6 center dot c) kJ center dot mol(-1) increase with increasing molar concentration of titanium c.
