Latest Patents

Robillard holds a patent for a method of making large particle size, high purity dense silica. This patent describes a process where tetraethylorthosilicate ethanol solution is added to a 2N ammonium hydroxide solution containing silicic acid with an average particle size of about 15 micrometers. The process involves forming a precipitate, digesting it in the solution, filtering through a screen with 45 micrometer openings, and drying to create a powder. The dried powder is then calcined in an oxygen atmosphere and densified by heating at approximately 1200°C in air, resulting in a large particle size, high purity, dense silica. This innovative method showcases her expertise in chemical engineering and materials development.
