Non-Spherical Silica Sol, Process for Producing the Same, and Composition for Polishing |
摘要 |
Provided is a non-spherical silica sol containing non-spherical silica fine particles dispersed in a dispersion medium, the non-spherical silica fine particles having an average particle diameter in a range of 3 to 150 nm as measured by dynamic light scattering, a minor-diameter/major-diameter ratio in a range of 0.01 to 0.8, and a specific surface area in a range of 10 to 800 m2/g, and also having a plurality of wart-like projections on the surfaces thereof, and a process for producing the non-spherical silica sol. The non-spherical silica fine particles contained in the non-spherical silica sol have a unique structure different from the structure of ordinary non-spherical silica fine particles. |
