本文用X射线衍射和微探针分析研究了Gd-Ni-Si系在1070 K下的相组成。已知化合物的存在，即：GdNi 10 Si 2、GdNi 8 Si 3、GdNi 5Si 3、GdNi 7Si 6、GdNi 6Si 6、GdNi 4Si、GdNi 2Si 2、GdNiSi 3、Gd 3 Ni 6Si 2、GdNiSi、GdNiSi 2、GdNi0.4Si1.6、Gd2Ni2.35Si0.65、Gd 3 NiSi 2、Gd 3 NiSi 3和Gd6Ni1.67Si3。此外，该系统还确定了五个新阶段。其中四种的晶体结构已经确定：Gd 2Ni 16 −12.8Si1−4.2（Th 2 Zn 17型）、GdNi6.6Si6（GdNi 7Si 6型）、Gd 3 Ni 8 Si（Y3 Co 8 Si型）和Gd3Ni11.5Si4.2（Gd 3Ru 4Ga 12型）。化合物~ Gd_2Ni_4Si_3的结构仍不清楚。在1070 K时，GdNi_5，GdNi_3，GdNi_2，GdNi，GdSi_2和GdSi_（1.67）等二元化合物形成了准二元固溶体，而Gd-Ni-Si系的其它二元化合物则没有明显的固溶性，本文还研究了GdNi_（6Si）_6，GdNi_（6.6Si）_6和Gd_3Ni_（11.5Si）_（4.2）化合物的磁性。
The Gd–Ni–Si system has been investigated at 1070 K by X-ray and microprobe analyses. The existence of the known compounds,i.e.: GdNi10Si2, GdNi8Si3, GdNi5Si3, GdNi7Si6, GdNi6Si6, GdNi4Si, GdNi2Si2, GdNiSi3, Gd3Ni6Si2, GdNiSi, GdNiSi2, GdNi0.4Si1.6, Gd2Ni2.35Si0.65, Gd3NiSi2, Gd3NiSi3and Gd6Ni1.67Si3, has been confirmed. Moreover, five new phases have been identified in this system. The crystal structure for four of them has been determined: Gd2Ni16−12.8Si1−4.2(Th2Zn17-type), GdNi6.6Si6(GdNi7Si6-type), Gd3Ni8Si (Y3Co8Si-type) and Gd3Ni11.5Si4.2(Gd3Ru4Ga12-type). The compound with composition ~Gd2Ni4Si3still remains with unknown structure. Quasi-binary phases, solid solutions, were detected at 1070 K to be formed by the binaries GdNi5, GdNi3, GdNi2, GdNi, GdSi2and GdSi1.67; while no appreciable solubility was observed for the other binary compounds of the Gd–Ni–Si system.Magnetic properties of the GdNi6Si6, GdNi6.6Si6and Gd3Ni11.5Si4.2compounds have also been investigated and are here reported.
