Latest Patents

Guy Von Dardel's latest patents focus on the preparation and use of silica aerogel. His innovative method describes the creation of a substantially crack-free, preferably transparent block of silica aerogel. The preparation involves hydrolysis of a tetraalkoxysilane, specifically tetramethoxysilane, in methanol with ammonia as a catalyst. The resulting alcogel undergoes a meticulous aging process for approximately ten days, followed by washing to remove water. The alcogel is then treated in an autoclave, where a controlled temperature increase and pressure drop are applied to prevent cracking. This process requires a total treatment time of at least 24 hours. Additionally, a heat treatment at temperatures between 500°C to 750°C may be performed to enhance the aerogel's transparency.
