  • Publication number: 20200354225
    Abstract: Provided is a dispersion containing high-purity silica particles and a method for producing the same. A first solution containing a silane alkoxide and a second solution containing fine bubbles having an average bubble diameter of 40 nm to 10 ?m are mixed. Thus, the silane alkoxide is hydrolyzed without using an alkaline catalyst in a liquid phase containing the fine bubbles, so that uniform silica particles having an average particle size of 3 to 10 nm are produced. Further, hydrolysis is carried out by adding a hydrolyzable metal compound to the dispersion containing the silica particles in the presence of the fine bubbles and the alkaline catalyst. Thus, the silica particles are grown, so that a uniform silica-based particle dispersion containing particles having an average particle size of more than 10 nm and 300 nm or less is produced.
