Evaluating Refractory Properties - Resco Products

Refractory Properties. Refractory properties are broken into mechanical physical properties and high-temperature properties. Typically, refractory materials are characterized by density, strength, and response to heat treatment. Certain physical properties are also measured and recorded during manufacture and serve as a basis for quality control.
