The distribution of pores, based on spinodal phase separation in sodium borosilicate glasses that were rapidly quenched at different cooling rates, was investigated. The N 2 adsorption−desorption behavior of samples shows that the pore is of the micropore type with pore size <1 nm. The air-quenched samples (quenched at 10 K/s) have larger pore volume and surface area than roller-quenched samples (quenched at 10 6 K/s). This effect is explained by the amplitudes of a series of the spinodal decomposition waves that are formed under cooling and increase in the air-quenched samples. Therefore, the pore volume and surface area increase with decreasing cooling rate according to an acid-leaching model that is proposed in the present investigation.
