WHAT ARE REFRACTORY MATERIALS?

Refractory materials are heat-resistant substances capable of maintaining their strength and integrity under extreme temperatures, often exceeding 2000°C. Found in furnaces, kilns, reactors, and incinerators, these materials serve three primary functions:


  • Provide thermal insulation

  • Prevent heat loss

  • Protect equipment from thermal damage
