Abstract

Nano-titania, up to 8 wt%, was added to magnesite–dolomite refractory matrix. The phase and microstructure analyses of samples heated up to 1650 °C for 3 h were studied by XRD and SEM/EDS, respectively. The physical properties are reported in terms of bulk density, apparent porosity, and hydration resistance. In addition, the mechanical behavior was studied by a cold crushing strength (CCS), and flexural strength at 1200 °C test. As a result, it was found that the presence of nano-TiO2 in the magnesite–dolomite matrix induced titanates formation (Mg2TiO4 and CaTiO3), which improved the sintering process. Nano-titania influenced the bonding structure through a direct bonding enhancement. In general, the addition of 6 wt% of nano-TiO2 contributed to reach a maximum increment in physical and mechanical properties.
