Abstract

In the past few years much work has been done at Union College in attempting to determine the mechanism of the setting of silicic acid gels. All of this work, however, had been done in alkaline, weakly acid, or moderately acid solutions, and practically no investigation of silicic acid gels in very strongly acid solutions has been made. The purpose of this research was to undertake such an investigation The effect of temperature and pH upon the time of set was studies. Three different temperatures were used, and the pH of all gels are studied was below 1. Concentrated hydrochloric and concentrated sulfuric acids were used to obtain this low pH. The heat of activation was calculated from the data obtained.
