Abstract
The free energy change for the reduction-diffusion reaction which was used to prepare the DyFe2 Dy2O3(s) + 3Ca(g) + 4Fe(s) = 3CaO(s) + 2DyFe(2)(s) intermetallic compound powder was calculated. The reduction-diffusion exper iments were carried out at 1073, 1123, 1273 and 1373 K respectively using p owders of Dy2O3, iron, and calcium grains as raw materials. XRD and EDX ana lysis confirmed that DyFe2 was formed by the diffusion of Dy into Fe.
