Corrosion behavior of MgO/CaZrO3 refractory matrix by clinker

The corrosion behavior of a MgO/CaZrO3 refractory matrix by clinker of Portland cement is studied. The attack mechanism to substrates of 80% MgO and 20% CaZrO3 (wt.%) obtained from dolomite and ZrO2 mixtures and MgO and presintetized CaZrO3 mixtures is established. The results are discussed in term of the phase equilibrium diagram MgO–CaZrO3–(CaO)2SiO2–(CaO)3SiO2.
