Improving the Physical Properties of Silica Aerogels Using a 3-step Method

A better understanding of controlling the chemical process is needed to further reinforce the mechanical properties of silica aerogels, while retaining their other properties, especially their low thermal conductivities.
Patent Abstract: 
The proposed method involves 3 steps which provides better control of the cluster growth and formation of the gel network in an aerogel.
Hydrolyzing an organosilicate precursor to form silanol groups under acidic conditions - Condensing the silanol groups under basic conditions with the help of a catalyst to form a polymeric silicate having a diverse range of pore sizes - Gelling the polymeric silicate
