In this paper, we report a detailed morphological study and analysis performed on finely powdered magnetic alloy based on rare earth-transition metals, produced by hydrogen absorption-desorption cycles. We have analyzed the morphology of these particles by computing all the required morphological descriptors. The size of these particles ranges from 5 to 40 mu m. The values of the morphological descriptors lie very close to those corresponding to adipic acid powders produced by comminution which are reported in the literature. The main advantage of the hydrogen absorption-desorption process over the conventional powder production route (ball milling) is that the particles do not undergo oxidation.
