The compounds RENi(BN) with RE = Y, La, Ce, Pr, Tm and Yb were synthesized by solid state reactions from metal powders and α-BN at temperatures between 1000° and 1200 °C. In addition, the mixed phases (Ca,Yb)Ni(BN) and (Ca,Tm)Ni(BN) were synthesized. All products were characterized by powder XRD measurements and indexed isotypic with the structure of CaNi(BN), consistent with the tetragonal space group
RE=Y、La、Ce、Pr、Tm 和 Yb 的化合物 RENi (BN) 是由金属粉末和 α-BN 在 1000°C 和 1200°C 之间的温度下通过固态反应合成的。此外,还合成了混合相(Ca,Yb)Ni(BN)和(Ca,Tm)Ni(BN)。所有产品均通过粉末 XRD 测量进行表征,并与 CaNi (BN) 结构索引同型,与四方空间群 P4 / nmm 一致。(BN) 阴离子的键合条件在新的氮硼酸盐化合物 REM (BN) 的透视图中讨论,该化合物包含除 Ni 之外的过渡金属原子 (M)。
