Abstract

Silicic acid gels result from practically any sol of hydrated silica, merely with the lapse of time. The gel must, however, contain a large enough concentration of silica to give sufficient strength or rigidity for the gel to set. A sol which contains less than .5 percent SiO2 will give a very weak gel, or no gel at all. Sols which are strongly alkaline will not set at all.
