| Abstract: | The method for measuring the grain size and distribution of crystal particles in permanent magnetic ferrite materials by means of the optical microscopy and image processing technique,and its application effectiveness are introduced in this paper.The practice has shown that this method is quick and effective.To use this technique as the routine physical detection way in production of the permanent magnetic material will be rather favorable for adjusting the process conditions in time and controlling the product quality steadily. |
