  • Recent advances in silica-alumina refractory: A review ...

    2014-6-1 · Kolli et al. have elaborated refractory material from kaolin (39.87% of SiO 2; 38.36% of Al 2 O 3). The calcined grog at 1350 °C/1 h, was used as aggregates with granulometric distribution composed of fine fraction (size: 100–250 μm) and coarse fraction (size: 1000–2500 μm). Crude kaolin (size <75 μm) was also used as a binder.

    2008-12-1 · One of the most severe refractory degradation mechanisms is spalling, which can occur by either volume-expansion phenomena (compressive stresses) or by volume-shrinkage phenomena (tensile stresses). A volume-shrinkage model is benchmarked to high-chromia refractory material properties and performance under gasifier operating conditions.
