ABSTRACT Refractories are ceramic materials possessing high thermal shock properties and slag corrosion resistance, as well as creep resistance at high temperatures. They are used in large quantities in steel making furnaces, metal smelting vessels, and glass melting tanks, and are made from very refractory minerals such as lime, periclase, corundum, spinel, and zirconia. Slags are residual vitreous materials generated during steel refining processes. They cover a wide range of compositions and may contain pure oxides, silicates, and sulfides as well as fluoride phases, depending on the melting and smelting processes....
