The explanation of ternary compounds, forming with AlB2 structure type in the rare earth metal-transition metal-silicon systems, implements on base of analysis of the dependence of the valence-electron concentration versus the kind of the transition metals in their solid solutions in the binary compounds with AlB2, _-ThSi2, and _-GdSi2 structure types appropriate to the rare earth-silicon systems. There is shown that the silicon content (as the electron donor) during formation of the ternary compounds with AlB2 structure type is dependent on the kind of transition metal and this content is decreased in the series of the compounds with Fe, Co, Ni, and Cu consecutively. The experimental data on concentrational intervals of the stability ranges of these ternary compounds are proposed to the qualitative evaluation of the effective valency of the transition metal atoms.
