| Abstract: | Porous glass based on sodium borosilicate glass was prepared. The procedures include phase separation and acid treatment. The adsorption properties of the porous glass were characterized by adsorptiion isotherm,specific surface and pore distribution with the help of N2 adsorption. The effect of thermal treatment time and tempreture on distribution of pore diameter and porosity were studied.The changing law of pore diameter with changing thermal treatment time and temperature was summerized. |

| Keywords: | porous glass thermal treatment pore distribution porosity |
