Raw materials for the refractory industry are materials made on the basis of mineral raw materials. They are characterized by the ability to maintain their functional properties without significant damage under various service conditions at high temperatures. They are used for carrying out metallurgical processes (melting, roasting, annealing, evaporation, distillation), designing furnaces, high-temperature units (reactors, engines, structural elements, etc.)
Refractory materials can be divided into two main groups:
