Refractory materials are used in various equipment where protection from long exposure of high temperatures, various melts, slags and hot gases is required. At the same time, the products should maintain their operational properties for a maximum time.


Accordingly, the following requirements are imposed on refractory materials:

  • corrosion resistance, resistance to melts and slags;
  • mechanical strength;
  • wear resistance;
  • resistance to heat shock (heat resistance);
  • fire resistance;
  • stability of shape and strength preservation to the maximum operating temperature;
  • non-wetting by various melts;
  • low weight;
  • high degree of reliability and economy in operation.
