Title: Innovations of John E Landmesser
Introduction
John E Landmesser is a notable inventor based in Monroeton, PA (US). He has made significant contributions to the field of materials science, particularly in the recovery of valuable metals. With a total of 3 patents to his name, Landmesser's work has implications for both industry and research.
Latest Patents
One of Landmesser's latest patents is focused on the recovery of tungsten and rhenium. This process involves firing a tungsten and rhenium source in an oxidizing atmosphere at high temperatures. The method effectively converts these metals into their respective oxides, allowing for the removal of a portion of rhenium as volatilized oxide. The result is a first fired material that contains essentially all of the tungsten and the remaining rhenium. The process further increases the surface area of the oxidized tungsten and ensures the removal of the remaining rhenium, resulting in an essentially rhenium-free oxidized tungsten.
Another significant patent is the controllable nitrate fusion process. This innovation converts tungsten-bearing material into sodium tungstate. The process involves adding an oxidizing reactant in small increments to a heated mixture of fused sodium hydroxide and tungsten-bearing material. The temperature is carefully maintained between 500°C and 700°C to achieve optimal results.
