Abstract

Thermo-decomposition of precursor complexes was utilized to synthesize scandia-stabilized zirconia (ScSZ) with the composition (Sc₂O₃)_0.08(ZrO₂)_0.92. Mixtures of precursors with different contents of EDTA (ethylenediaminetetraacetic acid) were synthesized through a homogenous soft chemical process, enabling the influences of ligand content on the calcination and sintering behaviors to be investigated. ScSZ polycrystals in a predominately cubic and rhombohedral polyphase were obtained after sintering at 1300 °C for 6 h.
