| Abstract: | The electrotransport velocities of carbon, nitrogen, and oxygen in alpha and beta hafnium were determined for the temperature
range of 1650 to 2130°C. Diffusion coefficients and effective valences were also obtained for each solute. These data were
used to predict the degree of purification achievable in a hafnium rod after electrotransport at 2000°C for different times.
A comparison was made between the predicted and experimentally observed results.
