One-step manufacturing process for neodymium-iron (magnet-grade) master alloy

Neodymium iron boron magnet has registered heightened demand due to its rapidly increasingly application in the clean energy sector. These magnets are manufactured by melting the mixture, consisting of neodymium, iron and boron followed by casting into ingots. The ingots are subsequently pulverized...
