The Real Enemy of refractory materials is not high temperatures,but sudden Temperature Change (Thermal Shock)

High heat alone is not the biggest problem for refractories. Rapid heating or cooling -- known as thermal shock--causes internal stress, cracking, and spalling. Even materials that handle 1600°C can fail quickly under sudden temperature changes.

Alumina Castable – For Fire-facing Walls in Tight Gas Combustion Chambers

Case Study: In tight gas drilling operations, structural materials for combustion chambers must withstand high-temperature shocks during blowout operations. Researchers prepared a refractory castable using white corundum as aggregate and aluminate cement as a binder.
