16 - 021The 773 K Isothermal Section of the Sm–Co–Si Ternary System.— The 773 K section of the phase diagram of the title system consistsof 30 three-phase regions. Seven ternary compounds are detected, the sixknown compounds SmCoSi, SmCoSi2, SmCoSi3, SmCo0.4Si1.6, SmCo2Si2, andSmCo9Si2, and the new compound SmCo9Si4. The new phase has a tetragonalstructure, space group I4/mcm, and is isotypic with NdCo9Si4. — (HE, WEI;ZENG, LINGMIN; ZHUANG, YINGHONG; WU, ZIQIN; J. Alloys Compd.298 (2000) 1-2, 173-176; Cent.
