Title: Innovations of Jean Deville in Alumina Production
Introduction
Jean Deville is a notable inventor based in Aix-en-Provence, France. He has made significant contributions to the field of alumina production, holding a total of 2 patents. His work focuses on innovative processes that enhance the efficiency and quality of alumina used in ceramics.
Latest Patents
One of his latest patents involves the production of calcined alumina with a controlled crystallite size. This invention outlines a process for producing alumina for ceramics by calcining alumina trihydrate in the presence of a mineralizer, such as a halogenated compound or a boron compound. The resulting calcined alumina consists of friable agglomerates of alpha alumina crystallites, which can be tailored to have a narrow distribution of sizes. The calcining process is conducted in an industrial kiln under a renewed oxidizing atmosphere at temperatures ranging from 800°C to 1300°C for a duration of 0.5 to 4 hours.
Another significant patent by Deville is a process for removing iron from sodium aluminate liquors obtained from the Bayer process. This method includes several steps, such as grinding and desilicatation, followed by an attack at elevated temperatures to make alumina hydrate soluble. The process results in an insoluble suspension of red mud, which can be separated from the supersaturated sodium aluminate liquor.
Career Highlights
Jean Deville has been associated with Aluminium Pechiney, a prominent company in the aluminum industry. His work has contributed to advancements in alumina production techniques, making them more efficient and effective.
