Abstract
Reactions among Si3N4, SiC, ZrC, ZrN and C were investigated under 1 atm N2 at 1650°C. Compatibility relations among the compounds coexisting with 1 atm N2 in the system Si-Zr-C-N were determined. Equilibrium states were confirmed by the fact that reaction products obtained from nitridation reactions were identical with those from decomposition of nitrides and by thermochemical calculation. The reaction products obtained from the starting sample of ZrC-Si3N4, were zirconium carbonitride and SiC, and those from ZrN-SiC were zirconium carbonitride and Si3N4. The lattice parameter of the zirconium carbonitride varied with the composition of the starting sample. The isobaric and isothermal section of the system Si-Zr-C-N includes 2 three-phase triangles.
