Title: The Innovations of Robert A. Wiles
Introduction
Robert A. Wiles is an accomplished inventor based in Hamburg, NY (US). He holds three patents that showcase his expertise in materials processing and chemical engineering. His work has significantly contributed to advancements in the fabrication of specialized materials used in various technological applications.
Latest Patents
One of Wiles' latest patents focuses on the recovery of gadolinium and gallium oxides, specifically Gd.sub.2 O.sub.3 and Ga.sub.2 O.sub.3. These materials are essential for the production of Gd.sub.3 Ga.sub.5 O.sub.12 (GGG) wafers, which serve as substrates for bubble domain memory devices. The innovative process he developed addresses the issue of waste generated during production, where approximately 25% of the starting material becomes contaminated 'saw kerf'. Wiles' method allows for the reprocessing of this waste, enhancing the economic viability of GGG wafer production. His process involves dissolving the 'saw kerf' in HCl, treating it with H.sub.2 SO.sub.4, and separating the resulting sulfates. Through metathesis with (NH.sub.4).sub.2 C.sub.2 O.sub.4, he converts the sulfates into ammonium oxalates, which are then calcined to yield high-purity Ga.sub.2 O.sub.3 and Gd.sub.2 O.sub.3. This process can also be adapted to recycle by-products from other grinding and polishing operations, potentially recovering up to 80% of generated waste.
Another significant patent by Wiles involves a novel process for producing 1,2-dichloro-1,1,2,2-tetrafluoroethane. This process is designed to produce the compound with minimal contamination from the 1,1-isomer. By contacting an organic feed composition with hydrogen in the presence of a hydrodechlorination catalyst, Wiles' method selectively degrades the undesired isomer, resulting in high-purity 1,2-isomer production.
