Abstract

Phase equilibria in the ternary systems Sc-Si-N, Ce-Si-N and Ho-Si-N at 1000 °C and the binary boundary system Ho-Si are investigated. No new binary or ternary phases are found. In all three systems the respective rare-earth mononitride dominates the ternary phase fields and, with the exception of HoSi2 in the Ho-Si-N system, coexists with all binary suicides. Thus Si3N4 is decomposed in contact with either scandium, cerium or holmium with the formation of ScN + ScSi2−x, CeN + CeSi2 and HoN + HoSi2−x, respectively.
