对使用60 wt% Sm-40 wt% Co烧结助剂的Sm 2Co 17的液相烧结进行了初步研究。通过添加烧结助剂，总钐含量从25.3重量%变化到34.5重量%，烧结磁体中存在的所得相是不确定的。烧结温度在1110°C至1140°C之间变化，烧结时间为30分钟。除饱和感应强度Bs下降约20%外，磁性能随钐含量的增加而增加。内禀矫顽力Hci增加了18倍，而矫顽力Hc和能量积（BH）max各增加了约6倍。剩余感应强度Br也增加，但仅增加约20%。最好的初始结果产生具有以下性质的磁体：Br = 6.0 kG，Hc = 3.8 kOe，Hci = 9.0 kOe和（BH）max = 6.4 MGOe。
An initial investigation of the liquid phase sintering of Sm2Co17 using a 60 wt% Sm ‐ 40 wt% Co sintering aid has been conducted. The total samarium content was varied from 25.3 wt% to 34.5 wt% through sintering aid additions, with the resulting phases present in the sintered magnets being uncertain. The sintering temperature was varied from 1110°C to 1140°C for a sintering time of 30 minutes. With the exception of the saturation induction, Bs, which decreased approximately 20%, the magnetic properties increased with increasing samarium content. This was particularly true of the intrinsic coercive force, Hci, which increased as much as eighteenfold, while the coercive force, Hc, and the energy product, (BH)max, each increased approximately sixfold. The residual induction, Br, also increased, but only by approximately 20%. The best initial results yielded a magnet with the following properties: Br = 6.0 kG, Hc = 3.8 kOe, Hci = 9.0 kOe and (BH)max = 6.4 MGOe.
