Impedance measurements and chronopotentiometry methods were used to investigate the diffusion of Bi3+ in the melt. The impedance technique yielded a diffusivity of 1.38 x 10-5 cm2/s at 450C and an activation energy of 7.6kcal/mol. The chronopotentiometric technique yielded corresponding figures of 1.30 x 10-5cm2/s and 7.1kcal/mol.
