High-temperature phase relations of ZrN–ZrO2–Y2O3 ternary system
Source abstract
Abstract
Zirconium nitride (ZrN) ceramics were prepared via hot pressed sintering (HP) at 1750 °C in N2 atmosphere with ZrO2–Y2O3 as sintering additive. X-ray diffraction was applied to analyze the phase composition of the as-prepared ceramics to study the high temperature phase relation in ZrN–ZrO2–Y2O3 ternary system and establish ZrN–ZrO2–Y2O3 ternary phase diagrams. The results show that ZrN and tetragonal ZrO2 (t-ZrO2) solid solution, face-centered cubic ZrO2 (c-ZrO2) solid solution, body-centered cubic Y2O3 (c-Y2O3) solid solution coexist in the system of ZrN–ZrO2–Y2O3.
