Latest Patents

Hirokatsu Hayashi holds a patent for a "Cake of easily dispersible precipitated silica." This invention describes a method for creating a cake of precipitated silica with a BET specific surface area of at least 220 m²/g. The cake can be dispersed in ion-exchange water to form an aqueous dispersion with a concentration of 5% by weight, which can be further diluted to 1.5% by weight. The resulting dispersion exhibits a light-scattering index (n-value) of at least 2. The process involves the simultaneous addition of an alkali silicate and a mineral acid to a reaction liquid, maintaining a pH between 7.5 and 11.5 and a temperature of 92-98°C. This innovative method allows for the efficient separation of precipitated silica from the reaction liquid in a wet state.
