摘要：
The diffusivity of oxygen in liquid tellurium and tellurium antimony alloys was determined from potentiostatic experiments. In the temperature range 773-923 K the diffusivity of oxygen in liquid tellurium is: D-0(Te) = (6.8.10(-2))exp(-19417/RT) [cm(2).s(-1)] while the isothermal D-0(Te) vs. alloy composition plot shows an s-shape dependence with a sudden rise in oxygen diffusivity around the alloy composition X(Te) = 0.3.
