With a total of 2 patents, Fitzpatrick's work showcases his expertise and innovative approach to solving complex problems in material production.

Latest Patents

Fitzpatrick's latest patents include a "Method of making high purity dense silica of large particle size." This method involves mixing tetraethylorthosilicate with ethanol and adding it to a dilute acid solution with a pH of about 2.25. The resulting solution is digested for approximately five hours, after which 2N ammonium hydroxide is added to form a gel at a pH of 8.5. The gel is then screened, vacuum baked, calcined in an oxygen atmosphere, and heated to about 1200°C in air to produce high purity, dense silica with large particle size. Another patent is titled "Method of making large particle size, high purity dense silica." In this process, a tetraethylorthosilicate ethanol solution is added to a 2N ammonium hydroxide solution containing silicic acid with an average particle size of about 15 micrometers. This forms a precipitate that is filtered, dried, and calcined to achieve the desired silica properties.
