- Аннотация: Phase relations have been established in the ternary system Ce-Ir-Si for the isothermal section at 950 °C based on X-ray powder diffraction and EMPA on about 80 alloys, which were prepared by arc melting under argon. From the 15 ternary compounds observed at 950 ºC 8 phases have been reported earlier. The crystal structures for 6 new ternary phases were assigned to known structure types based on XPD Rietveld refinements. Structural chemistry of these compounds follows the characteristics already outlined for their prototype structures: 3 – Ce3IrSi3 (Y3NiSi3 - type), 7 – Ce3Ir2Si2 (Sm3Ir2Si3 - type), 9 – Ce3Ir4Si4 (U3Ni4Si3 - type), 11 – Ce3Ir3Si2 (Ce3Rh3Si2 - type), 14 – Ce6Ir30Si19 (Sc6Co30Si19 – type), and 15 – Ce2Ir12Si7 (Ho2Rh12As7 - type). The crystal structure of 1 – Ce4Ir27Si69 (at. %) is unknown.
