As-prepared AlPO&#x2014;BO&#x2014;NaO-based glasses were placed in an autoclave together with distilled water and were treated at 150&#xb0; C. for two hours. Although the specific surface area of the as-prepared glass prior to autoclave treatment was negligibly small, the autoclave treatment dissolved most of the borate component and the sodium component to obtain a mesoporous material having a specific surface area of 236 m/g and a pore size distribution of 5 to 10 nm. This mesoporous material is hydrophobic and has weak solid acidity and small polarity.
