Abstract
This work is a comparative study of MgO/MgAl2O4 refractory nanocomposites synthesized by three different liquid phase methods. Physical–chemical and microstructural characteristics of the refractories have been characterized in terms of bulk density, apparent porosity, water adsorption capacity, crystalline phases, crystallite size, particle size distribution, morphology and composition. The mechanical behavior of the synthesized samples was evaluated in terms of bend strength and cold compressive strength. The thermal expansion coefficients of the MgO/MgAl2O4 refractories were also measured from room temperature to 1200 °C.
