Abstract
Destructive processes in refractory materials associated with thermal cycling (sharp heating and cooling) are discussed. A method for evaluating the thermal resistance of unshaped refractory materials is proposed that is based on the determination of a structure variation factor; a criterial formula for quantitative evaluation of the thermal stability of refractory materials at different thermocycling temperatures is derived.
