Abstract

Porous materials were prepared from colored waste glass by hydrothermal treatment with Na 2CO 3 aqueous solution. The resultant specific surface area was approximately 140 m 2/g at maximum. Specific surface area increased at first, reached a maximum, and decreased gradually to be constant at approximately 60 m 2/g depending on the period of hydrothermal treatment, irrespective of the concentration of Na 2CO 3 aqueous solution. However, the period at which the specific surface area reached maximum shortened with an increase in Na 2CO 3 concentration. On the other hand, the mass of the sample decreased and eventually saturated at approximately 30 mass% of the initial weight during the hydrothermal treatment. Both the dissolution of the mother glass and the formation of crystalline deposits, which were identified as calcite, zeolite-P and analcime, affected the porous structure of the treated samples.
