The effect of microsilica and refractory cement content on the properties of andalusite based Low Cement Castables used in aluminum casthouse O efeito do teor de microsílica e de cimento refratário nas propriedades de LCCs usados em moldagem de alumínio

Cerâmica, 2010
The bonding system in low cement castables is achieved by the use of calcium aluminate cement, microsilica and reactive alumina. The lime/silica ratio critically impacts the liquid phase formation at high temperatures and subsequently the corrosion ...

Effect of Carbon Black Content and Firing Atmosphere on the Properties and Microstructure of Al₂O₃-SiC-C Castables. [PDF]

Materials (Basel)
Al2O3-SiC-C (ASC) castables containing spherical asphalt are widely utilized in high-temperature metallurgical furnaces because of their good abrasive resistance and slag resistance; however, the release of hazardous benzopyrene during the pyrosis ...

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.

Phase Transformations and Properties Evolution of Alumina-Based Refractory Castables Containing ZnO and SiO2

Materials Research, 2022
Although most of the studies presented in the literature are focused on MgAl2O4 formation and its role on alumina-based refractories performance, ZnO has been reported as a promising spinel inducer. Aiming to investigate the influence of ZnAl2O4 (ZA) and
