Impact of synthetic route on the structural and microstructural changes in the ZrO2-CaO system

In the presented research we investigated phase development in the ZrO2-CaO system during the thermal treatments up to 1000 °C. The precursors of ZrO2-CaO system covering the whole concentration range were prepared using two synthetic routes: co-precipitation from aqueous solutions and ball milling of the corresponding nitrate salts. The obtained precursors were calcined in the air at temperatures of 400 °C, 600 °C, 800 °C and 1000 °C and analysed at room temperature using XRD, Raman spectroscopy, FE-SEM and EDS.
