Abstract
The present invention relates to a silica particle dispersion including spherical silica particles and a solvent, in which the spherical silica particles have a median diameter d50 of 0.5 μm to 20 μm, and a product A×d50 of 2.7 μm·m2/g to 5.0 μm·m2/g, the product A×d50 being a product of a specific surface area A (m2/g) of the spherical silica particles and the median diameter d50 (μm).
Claims9
A silica particle dispersion comprising spherical silica particles and a solvent, wherein the spherical silica particles have a median diameter d50 of 0.5 μm to 20 μm, and a product A×d50 of 2.7 μm·m2/g to 5.0 μm·m2/g, the product A×d50 being a product of a specific surface area A (m2/g) of the spherical silica particles and the median diameter d50 (μm).
A method for producing a silica particle dispersion, the method comprising:
- mixing a solvent with powder of spherical silica particles, the spherical silica particles having a median diameter d50 of 0.5 μm to 20 μm and a product A×d50, which is a product of a specific surface area A (m2/g) and the median diameter d50 (μm), of 2.7 μm·mm2/g to 5.0 μm·m2/g;
- and
- subjecting the mixed liquid to dispersion treatment, followed by classifying to remove aggregates of the spherical silica particles.
