With a total of three patents to his name, Greber's work showcases innovative methods that enhance the properties and applications of ceramic materials.
Latest Patents
Greber's latest patents include a method for the manufacture of transparent aluminum oxide ceramic. This method involves sintering dry-pressed acid-containing aluminum oxide monohydrate in a vacuum or hydrogen environment. The process begins with the peptization of aluminum alkoxide using a mixture of water and acid vapor, allowing for easier separation of the monohydrate crystals in water. The resulting product, with an acid content ranging from 12 to 25%, is suitable for forming transparent ceramic articles without the need for calcination.
Another significant patent involves resinous compositions containing modified alumina hydrate crystals. This invention focuses on a modified form of alumina hydrate filler that improves the workability and mechanical properties of thermosetting and thermoplastic compositions. The modified alumina hydrate crystals have rounded edges and a mean crystal size of less than 35 microns, resulting in compositions with enhanced viscosity properties, good bending strength, and flame retardant characteristics.
