Nd2Fe14B particles were obtained from mixture of neodymium oxide, iron oxide, boric acid and CaH2 by reductiondiffusion process. Two different washing processes were used for the separation of magnetic particles from Ca and CaO matrix: usual washing with water and planetary ball milling process in ethanol media. Nd2Fe14BHx hydrogenated state was formed after .

· DEFINITON: • A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering etc. 6. PRINCIPLE: A ball mill works on the principle of impact and attrition. size reduction is done by impact as the balls drop from near the top of the shell.

· When the ballmilling time is less than 48 h, no V 2 O 3 particle is observed, and when the ballmilling time is up to 60 h, black granular V 2 O 3 particles can be observed in the two alloys. The black granular particles are uniformly distributed in the matrixes, suggesting the highly active element V reacted with O 2 and formed the V 2 O 3 in the ball milling process.
