There is provided a process for using amphiphilic compounds in preparing new classes of crystalline oxide materials. These oxide materials may have uniformly large pores, e.g., having a size of about 40 Angstoms in diameter. This process involves combining sources of oxides with micellar solutions of organic amphiphilic compounds, such as quaternary ammonium cationic surfactants. Aggregates of these micelles in the form of liquid crystals are believed to function as templates for the formation of the present highly porous, crystalline materials. |
