Scope
This standard specifies the determination method of the average particle size and particle size distribution of samarium-cobalt permanent magnet alloy powder.
This standard is applicable to the determination of the average particle size of single samarium-cobalt 1:5 and 2:17 rare earth permanent magnet alloy powders by Fe's method, and laser particle size distribution determination. The average particle size determination range is 2.0 μm~25.0 μm, and the particle size distribution determination range is 0.2 μm~875 μm.
