Title: The Innovative Contributions of Donald E. Stowell
Introduction
Donald E. Stowell is a notable inventor based in Ponca City, Oklahoma. He has made significant contributions to the field of materials science, particularly in the development of alumina powders and spheres. With a total of six patents to his name, Stowell's work has had a lasting impact on various industrial applications.
Latest Patents
Stowell's latest patents include innovative methods for enhancing the properties of alumina materials. One of his notable inventions is a method for increasing the pore volume of alumina powder produced by spray drying alumina slurries. This process involves heating the slurry to a temperature near the boiling point of water and applying pressure up to the critical point of water. By introducing the slurry to a spray drying chamber through a small orifice, he creates a backpressure that exceeds the slurry vapor pressure, resulting in improved material characteristics. Another significant patent involves the production of high-strength alumina spheres through hydrogelling. This method produces alumina spheres with high crush strength by hydrogelling low viscosity acidified alumina slurries in a surfactant-containing ammonia solution.
