  • Hollow silica particles and method for producing the same
    Patent number: 8992873
    Abstract: The present invention provides a method of producing hollow silica particles. First, an amine-ketimine compound is mixed with water to obtain a hydrophobic core dispersion, and then an organic siloxane compound and/or a coupling reagent is added into the hydrophobic core dispersion to form a core-shell silica dispersion. Then, the core-shell silica precipitate is separated from the core-shell silica dispersion, and then it is further dispersed and washed by a low carbon alcohol solution. Finally, hollow silica particles in accordance with the present invention are produced. In addition, the present invention also provides hollow silica particles produced by the afore-mentioned method without using any additional surfactant.
