Title: Herbert Giesche: Innovator in Spherical SiO₂ Particle Technology
Introduction
Herbert Giesche is a notable inventor based in Munich, Germany. He has made significant contributions to the field of materials science, particularly in the development of spherical SiO₂ particles. With a total of 2 patents, Giesche's work has implications in various applications, including chromatography.
Latest Patents
Giesche's latest patents focus on the preparation of highly monodispersed nonporous spherical SiO₂ particles. These particles have mean diameters ranging from 0.05 to 10 µm, with a standard deviation of not more than 5%. The innovative method for producing these particles involves a two-step process. Initially, a sol of primary particles is created through the hydrolytic polycondensation of tetraalkoxysilanes in an aqueous/alcoholic ammoniacal medium. Subsequently, the SiO₂ particles are refined to the desired size through a controlled addition of tetraalkoxysilane or organotrialkoxysilane, based on the reaction's extent. The resulting SiO₂ particles are particularly valuable as sorption materials in chromatography.
