<P>PROBLEM TO BE SOLVED: To provide a silica gel capable of precisely controlling physical properties such as pore diameter, capable of designing an ionic conductor while making good use of these physical properties, having a large pore volume and suitably usable as a carrier of an ionic conductor into which an adequate amount of an ionic conductive compound can be incorporated. <P>SOLUTION: The silica gel has (a) 0.3-3.0 ml/g pore volume, (b) 200-1,000 m<SP>2</SP>/g specific surface area and (c) less than 20 nm maximum diameter (D<SB>max</SB>) of pores, (b) it is amorphous, and (e) when chemical shift of Q<SB>4</SB>peak in solid Si-NMR is represented by δ(ppm), δ satisfies the expression -0.0705×(D<SB>max</SB>)-110.36>δ. <P>COPYRIGHT: (C)2004,JPO |
