  • 13 Types of Refractory Materials and Their Applications

    Monolithic refractory, the name generally given to all unshaped refractory products, are materials installed as some form of suspension that ultimately harden to form a solid mass. Monolithic refractories are replacing the conventional type fired refractories at a much faster rate in many applications including those of industrial furnaces.
