Title: Da-Hung Yang: Innovator in High Solids Aqueous Silica Slurry Technology
Introduction
Da-Hung Yang is a notable inventor based in Hudson, OH (US). He has made significant contributions to the field of materials science, particularly in the development of high solids aqueous silica slurries. His innovative work has led to the creation of a patented technology that enhances the properties and applications of silica slurries.
Latest Patents
Yang holds a patent for a "High solids aqueous silica slurry." This invention describes high solids aqueous slurries of amorphous precipitated hydrated silica, characterized by relatively low viscosity. The slurry typically contains between 40 to 60 weight percent of hydrated precipitated high structure silica, with a viscosity of less than 1000 centipoises. The patent outlines processes for producing this aqueous high solids silica slurry, including methods for liquifying a wet cake of amorphous precipitated hydrated silica and wet milling it to achieve a median agglomerate particle size between 0.3 and 3 microns. The resulting high solids slurry can be shipped in bulk with only mild agitation to prevent setting, and a dispersant may be added to retard settling.
