The system Clinker–MgO–CaZrO3 and its application to the corrosion behavior of CaZrO3/MgO refractory matrix by clinker

Phase relations in the clinker-rich region and the limits between the different stability fields of the isothermal section Clinker (CK)–MgO–CaZrO3 at 1500 °C were experimentally established. The corrosion behavior by clinker of Portland cement of a CaZrO3-rich/MgO refractory matrix obtained from both natural and synthetic raw materials were also studied. The attack mechanism to CaZrO3-rich substrates was discussed in terms of microstructural features of the refractory matrix and the information supplied by the isothermal section Clinker–MgO–CaZrO3 at 1500 °C.
