Synthesis and Properties of Composite Stabilized ZrO₂

Abstract:

Through Mechanical grounding method, CaZrO₃ – 8YSZ(8% in mol yttria stabilized zirconia) electrolyte samples with different amounts of CaZrO₃ at 10wt%, 20wt%, 30wt% were sintered at different temperatures in Muffle furnace. The decomposition temperature of CaZrO₃ is 825°C-900°C under one atmosphere. At high temperature, CaZrO₃ decomposes into CaO and ZrO₂. So Y₂O₃-CaO-ZrO₂ complex is composed. The effects of the sintering temperature and the contents of the CaZrO₃ on the conductivity, porosity, flexure strength, hardness were investigated. XRD and SEM were used to analyse the compositions and microcosmic morphology.
