Abstract
Hard magnetic material Nd2Fe14B was synthesized via powder metallurgy technique. The magnetic powder Nd2Fe14B was produced by mixing Neodymium powder (Nd), Iron powder (Fe), and Boron powder (B) in a vacuum and then followed by firing process at 720ºC. The Nd2Fe14B powder produced was grained with addition of 0.3g and 0.7g Neodymium respectively. The powder was sintered at 720ºC. The characterization of magnetic properties by using VSM and phase analyse using XRD. SC-70 was used as detector with 40 kV and 30 mA (CuKα/1.5418Ao). The scan range was 10o-90o with a speed of 2 deg/min. The crystal structure of the samples were determined based on data obtained from XRD pattern. The tetragonal crystal structure of Nd2Fe14B was confirmed with lattice parameters ‘a’ = ‘b’ = 8.707Å and ‘c’ = 12.203Å. The result showed that remanence magnetization (Mr). The maximum energy product (BH) max of Nd2Fe14B was increased from 8,56 KGOe to 16,59 KGOe with adddition of 0,3g Nd. The BHmax reached 17,83KGOe when 0,7g Nd-rich was introduced.
