A rapid synthesis of Nd2Fe14B nano powders was achieved by microwave irradiation to obtain oxide powders through varying microwave power and duration of microwave heating. The homogeneous oxide powders were then reacted with CaH2 through a reduction reaction at 700°C for 2hours, to obtain Nd-Fe-B po...
