Title: Yvon Lazennec: Innovator in Beta Alkaline Alumina Technology
Introduction
Yvon Lazennec is a noteworthy inventor based in St Michel sur Orge, France. With a total of six patents to his name, Lazennec has made significant contributions to the field of materials science, particularly in the development of technologies related to beta alkaline alumina, which hold promise in energy storage solutions.
Latest Patents
Among his most recent innovations, Lazennec has patented a method of preparing beta alkaline alumina parts. This invention focuses on creating solid electrolytes for sodium-sulphur electric cells. The method includes mixing alumina and an alkaline carbonate in precise quantities, heating the blend, crushing it after cooling, and shaping the resultant parts. A critical feature of this process is the deposition of an alkaline metal compound on the parts’ surface prior to sintering. This technique creates a sodium-rich atmosphere during sintering, which compensates for potential loss of sodium and minimizes the diffusion of the alkaline metal.
Additionally, he has developed another method for preparing alkaline beta alumina parts. This process involves heating a mixture of alumina and sodium carbonate and subsequently shaping and sintering the parts at high temperatures, specifically 1650 degrees Celsius. This advancement is particularly beneficial for manufacturing electrolytes used in sodium-sulphur cells.
