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.
