Homogeneous refractory materials are mechanical mixtures of refractory materials that act as aggregates, adhesives, metallic materials, or other desirable product properties. The mixing of materials causes physical and chemical reactions during installation and during the molding of prefabricated objects, not during use. Monolithic refractory differs from refractory bricks is that they are not cast or fired before use, although the chemical and physical properties show similar and sometimes bett
