Porous SiO2-ZrO2 glass was prepared from a sol containing polyethylene glycol (PEG) by the sol-gel method. After air-drying at room temperature, the gel was baked at 600°C. The ZrO2 content in the porous glass was 30wt%. The median pore diameter of the porous glass was 2nm regardless of the molecular weight and amount of PEG added. The reproducibility of the pore size distribution was good, and the pore volume and surface area were linearly proportional to the amount of PEG added. Alkali resistance of the porous glass was much larger comparing to the porous SiO2 glass.
