Effect of in-situ carbon containing calcium aluminate cement on properties of Al2O3-SiC-C based trough castables

Journal of Asian Ceramic Societies, 2020
The properties of Al2O3-SiC-C castables bonded by in-situ carbon containing calcium aluminate cement (CCAC) were investigated in this study. The results showed that after the Al2O3-SiC-C castables were dried at 110°C, their cold crushing strength (CCS ...

Crack-free caustic magnesia-bonded refractory castables [PDF]

Ceramics International, 2021
A growing interest in designing high-alumina MgO-bonded refractory castables has been identified in recent years due to the magnesia ability to react: (i) with water at the initial processing stages of these materials (inducing the precipitation of brucite phase) or (ii) with alumina, giving rise to in situ MgAl2O4 generation at high temperatures ...

Reasons for crack propagation and strength loss in refractory castables based on changes in their chemical compositions and micromorphologies with heating: special focus on the large blocks

Journal of Asian Ceramic Societies, 2019
Among the most significant problems in industrial refractory manufacture, especially of monolithic refractories, are the formation of cracks and loss of strength in green bodies or during heating of the refractory castables.
