SOLUTION: In this Sm-Fe-N series alloy powder, the average grain size is 0.5 to 10 μm and the coefficient of the acicular degree defined by following formula is >=75%, where the coefficient of the acicular degree (%)=(b/a)×100%, (a) = the longest size of the grain images and (b) = the maximum size vertical to (a). In the Sm2Fe17N3 alloy spherical grains, as the most preferable ranges, the average grain size is made to 0.7 to 4 μm and the coefficient of the acicular degree is made to >=90% by which its coercive force can be made to >=17 kOe and the residual magnetization can be made to >=130 emu/g. The alloy powder can be obtained by the following procedures. Sm as a rare earth element and Fe as a transition metal are dissolved in acid and Sm, Fe ions and a substance to form insoluble salt are allowed to react and are precipitated.  The precipitates are fired to make them into metallic oxide which is reduced.

IPC: G01F25/00
Filed: 1987-12-28
Abstract: PURPOSE:To eliminate variance in accuracy after measurement by pressing the top surface of filled granular substances after the measurement by using a plate, measuring the displacement of the compressed granules, and confirming whether or not the granules are measured by a prescribed amount. CONSTITUTION:The granular substances A which are measured and put in a quantitative measure 1 are pressed by the pressure plate 3 fitted to an actuator 2. Then the filing rate of the granules A is made constant by the compression of the granular substances A. Then the capacity of the granular substances compressed to the constant filling rate is measured as the displacement delta of a sinking quantity by the pressure plate 3, and it is confirmed whether or not the displacement value is within a set constant accuracy range permitted by capacity measurement. Then the accuracy is decided according to whether or not the displacement value is within the accuracy range to obtain the granular substances which are measured with good accuracy. Consequently, unstableness due to vibration need not be considered and the granules having accuracy are confirmed at low cost.
