Title:
SILICA PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/186468
Kind Code:
A1
Abstract:
The present invention addresses the issue of providing silica particles capable of providing a silica particle dispersion having good uniformity. These silica particles have an average primary particle diameter dBET calculated from specific surface area using the BET method of 1–100 nm and a ratio (dDLS/dBET) between the average secondary particle diameter dDLS measured using the dynamic light scattering method and the dBET of no more than 1.2. These silica particles ideally have a coefficient of variation for particle diameter of no more than 20%, as measured using a transmission electron microscope having a magnification of 200,000.
