PREPARATION OF POROUS MATERIAL FROM NATURAL CLAY AND SYNTHETIC SILICATE

Abstract

A porous material with smectite-type structure was prepared from natural clay (surface area of 13 m² g⁻¹ and pore volume of 0.12 cm³ g⁻¹) and silicate synthesized by hydrothermal method using water glass and magnesium chloride, and dimethyldistearyl ammonium chloride. The hydrothermally treated sample had large surface area (272 m² g⁻¹) and pore volume (0.55 cm³ g⁻¹) values because pores were formed between the stacking structure of clay and synthetic silicate fragments.
