Kind Code:
A1
Abstract:
Silica particles for which an alkoxy silane serves as the raw material, and which fulfill the following conditions (a)-(c). (a) The content of alkali metal elements is at most 5ppm relative to silica solids. (b) The moisture absorption at 50% relative humidity is at most 0.25mg/m2, and the refractive index measured by liquid immersion is 1.450-1.460. (c) The mean primary particle diameter as calculated from the specific surface area measured by nitrogen adsorption is 10-100nm.
