Low porosity of the refractory brick is desirable since it improves the mechanical strength and other properties of the refractories. True porosity of a refractory brick is the ratio of the total pore space (i.e. open and closed pores) of a body to its volume and is expressed in volume percent. The formula for true porosity is as follows.
