Dispersion liquid of silica particles and production method therefor |
| abstract |
Provided is a dispersion liquid of silica particles, comprising silica particles having an average particle diameter of 5 to 300 nm determined from an electron micrograph and a density of 1.20 g/cm3 or more determined from a specific surface area determined by a BET method using nitrogen adsorption, wherein the dispersion liquid has a pH of less than 8, a silica concentration of 12 to 40% by mass, and a viscosity in terms of a silica concentration of 20% by mass of 40 mPa·s or less. When this silica particle is used as an abrasive, it is possible to realize a sufficient polishing speed and a smooth polished surface on which occurrence of scratches is suppressed. |
