The interaction of the components in the Ce-Ru-Si system at 600 degrees C w
as investigated over the whole concentration range by X-ray powder and mono
crystal diffraction, metallography, and X-ray microprobe analysis. The form
ation of the previously reported phases, CeRu2Si2 and CeRu3Si2, was confirm
ed and six new ternary compounds were observed. The crystal structures of t
he compounds CeRuSi3, CeRuSi2, and CeRuSi were determined. (C) 1999 Elsevie
