| 7. | Both of the two ways can reach fb5b standard of tdk company . the coercive force of strontium permagnetferrite can be improved when a12o3 or cr2o3 was added to caco3 - sio2 or caco3 - hbo3 multi - additives . ( 4 ) comparing with normal caco3 and sio2 , the nano caco3 and sio2 improve the magnetic . for the nano caco3 and sio2 have high chemical activations and excellent distribution , the density of permagnetferrite can be improved and the sinter temperature of it can be reduced 纳米caco _ 3 、 sio _ 2与普通caco _ 3 、 sio _ 2加入相比,锶铁氧体永磁获得的最佳磁性能高,获得最佳磁性能的添加量范围变宽,即纳米caco _ 3 、 sio _ 2提高了磁性能的稳定性,有利于大生产时锶铁氧体永磁的磁性能的稳定,对生产有重要的指导四川大学硕士论文意义;由于纳米caco3 、 510 :分布更均匀,具有高的化学活性,降低了铭铁氧体永磁的最佳烧结温度,提高了铭铁氧体永磁的烧结密度,因而增大了caco3 、 510 :添加剂对铭铁氧体永磁的改性效果。 |
