Classification of porosities in refractories and their effects on properties
Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).
The first two types of stomata are commonly examined, known as apparent porosity.
The pores in refractory include open pores, through pores and closed pores.
