  • Evaluating Refractory Properties - Resco Products

    For refractories based on alumina materials, density generally increases with alumina content. Apparent porosity is a measurement of the volume of the open pores within a refractory. Since infiltrating materials from the process migrate through the pore structure, apparent porosity is a property to evaluate when selecting a refractory.
