Latest Patents

Kamiya's latest patents focus on a method for producing hollow silica particles. This innovative method aims to provide hollow silica particles with a dense silica shell layer. The process involves adjusting the pH of an oil-in-water emulsion containing an aqueous phase, an oil phase, and a surfactant to at most 3.0. Following this, a first silica material is added to the emulsion, and subsequently, a second silica material is introduced at a pH of at least 8, in the presence of alkali metal ions. This results in a hollow silica precursor dispersion, which is then processed to obtain hollow silica particles.
