Silica gel










Image Number 6 for United States Patent #7074376.

A method of producing a silica gel by hydrolyzing a silicon alkoxide and subjecting the resulting hydrogel to a hydrothermal treatment substantially without aging it is described. Also described in a silica gel produced by such a method and a silica gel which has the following characteristics: (a) the pore volume is from 0.6 to 1.6 ml/g, (b) the specific surface area is from 300 to 900 m.sup.2/g, (c) the mode diameter (Dmax) of pores is less than 20 nm, (d) the volume of pores having diameters within .+-.20% of Dmax is at least 50% of the total pore volume, (e) it is amorphous, and (f) the content of metal impurities is at most 500 ppm.
