Title: Innovations of Jean Charpin in Mineral Membrane Technology
Introduction
Jean Charpin is a notable inventor based in Paris, France. He has made significant contributions to the field of mineral membranes, holding a total of 4 patents. His work focuses on methods for manufacturing permeable mineral membranes, which have various applications in gas separation and filtration.
Latest Patents
One of Charpin's latest patents is a method of manufacturing permeable mineral membranes. This invention involves depositing a thin layer of gel of peptised hydroxide of at least aluminum on a permeable porous substrate. The resulting membrane is then dried and fired at temperatures ranging from 500°C to 1100°C. These membranes can be utilized for isotopic separation of gases or for filtration and ultrafiltration.
Another significant patent is the process for the production of porous, permeable mineral membranes. This process entails forming a thin layer of at least one mineral compound on a porous, permeable substrate. The mineral compounds used are chosen from simple or mixed metal oxides and hydroxides, excluding aluminum compounds. The suspension of ultrafine colloidal or non-colloidal particles allows for the creation of microporous layers with very small pore radii, eliminating the need for a compression stage.
