Tuning the structural and mechanical properties in ZrO 2 -SiO 2 binary system through Y 3 + inclusions

Abstract The present investigation explores the influence of yttrium (Y 3 + ) inclusions in ZrO 2 -SiO 2 binary system (YSZ) on its structural and mechanical features. The powders were synthesized through sol-gel technique and an exclusive characterization were undertaken to investigate the structural and mechanical features influenced by Y 3 + additions. Characterization techniques affirmed the crucial role of Y 3 + on the resultant structural and thermal stability of the YZS system. Instrumented indentation inferred the enhanced mechanical properties demonstrated by YZS system in comparison with pure ZrO 2 –SiO 2 binary system (ZS).
