Compressive strength is the ability of materials to withstand pressure in a high temperature environment, and bulk density reflects the density and quality of the material. The thermal expansion coefficient is the℃of volume change of a material when the temperature changes. A low thermal expansion coefficient helps to improve the thermal stability of the material.

Spalling usually occurs on the surface of refractory materials due to temperature changes, chemical reactions or mechanical stress, affecting the overall performance and service life of the material. In response to these problems, regular inspection and maintenance are required, and appropriate materials and construction processes should be selected to extend the service life of refractory materials.
