Title: Leroy D Hart: Innovator in Ceramic Fiber Technology
Introduction
Leroy D Hart is a notable inventor based in St. Louis, MO (US), recognized for his contributions to the field of ceramic materials. With a total of 2 patents, Hart has made significant advancements in the production and application of ceramic fibers.
Latest Patents
Hart's latest patents include innovative processes for the production of continuous ceramic fibers. This process involves extruding and attenuating thin continuous fibers or filaments made from alumina or other ceramic materials. These fibers are created from a slip that contains particles of the refractory material combined with selected resins or binders, specifically a high molecular weight linear chain polyethylene oxide polymer and an organic solvent. The fibers are then heated to produce a ceramically bonded refractory product. Another significant patent focuses on high strength alumina-silica catalyst substrates. These substrates are characterized by superior structural properties and high catalytic activity, achieved through a blend of colloidal silica and specially activated alumina, which is rehydrated and activated under specific conditions. The activation process occurs at temperatures between 1200°C and 1400°C, resulting in a substrate that is free from silica.
