Abstract:To investigate the action mechanism of titanium, the effects of different Ti-bearing compounds, including CaTiO3, MgTiO3, and nano-TiO2, on the properties of alumina–magnesia castables were studied. By analyzing the phase compositions, microstructures, and physical and mechanical properties of the castables, it was demonstrated that an intermediate product, CaTiO3, was first generated. This was then consumed by solid-solution reactions, and titanium was involved in the liquid formation as the temperature incre… Show more
“…Tang et al [10] investigated the influence of CaTiO 3 , MgTiO 3 and nano-TiO 2 additions on the physical and mechanical properties of alumina-magnesia castables in order to increase castable densification, thus, inhibiting the effects of CA 6 and spinel expansion. They found that MgTiO 3 is unstable in all tested materials, while 2 wt.% CaTiO 3 results in the best castable properties.…”
