利用ＨＤＤＲ法生产Ｎｄ－Ｆｅ－Ｂ系磁体粉末利用ＨＤＯＲ法生产的Ｎｄ－Ｆｅ－Ｂ系磁体粉末，是由非常微细的结晶颗粒（约０．３ｕｍ）所组成的粉末，具有很大的矫顽力。这种粉末大致是各向同性的，其最大碰能积约为１２ＭＧＯｅ，为了提高其最大磁能积可用Ｃｏ取代其中...
Nd-Fe-B based magnet powder produced by HDDR method Nd-Fe-B based magnet powder produced by the HDOR method is a powder composed of very fine crystalline particles (about 0.3 μm) and has a large coercivity force. This powder is generally isotropic, the maximum energy of its collision product is about 12MGOe, in order to increase its maximum energy product can be replaced with Co ...
