Abstract: The synthesis and characterization of the amorphous porous silica are reported in this paper. The silica was prepared by chemical precipitation from sodium silicate and chlorohydric acid in the presence of a surfactant, and the silica powders with a high specific surface area (>1300 m2/g) has a uniform pore diamater about 2.7 nm.

Key words: Silica, High specific surface area, Porous, Preparation
