    2013-12-24 · Refractories are made from abundant industrial minerals such as SiO2, Al2O3, MgO, dolomite and chromite for usage as insulation or molten metal/slag containers. These refractories have been engineered to meet different challenging specifications such as high temperature resistance, long service life, creep or spalling resistance, and economic savings. Most refractories are consumable materials which may last from few weeks to several years depending on service conditions and material performance. In general, spent refractories do not have much value after service, creating disposal issues. In some locations in the USA, companies may pay high fees to landfill spent refractories.
