Method of making ferrite material powder by spray pyrolysis process and method of producing ferrite magnet |
摘要 |
A method of making a magnetoplumbite-type ferrite material powder includes the step of preparing the ferrite material powder by spraying a mixed chloride solution, in which a chloride of iron and a chloride of strontium are dissolved, into a heated atmosphere. The solution of the mixed chloride contains 25% through 35% of the chloride of iron and 2.4% through 4.9% of the chloride of strontium. <IMAGE> |
