Title:
METHOD OF MAKING HYDROPHOBIC SILICA PARTICLES
Document Type and Number:
WIPO Patent Application WO/2017/166173
Kind Code:
A1
Abstract:
A method of making a plurality of non -crystalline hydrophobic silica particles, is provided, comprising: providing a plurality of hydrophilic silica particles; providing a water; providing an aldose; dispersing the plurality of hydrophilic silica particles in the water to form a silica water dispersion; dissolving the aldose in the silica water dispersion to form a combination; concentrating the combination to from a viscous syrup; heating the viscous syrup in an inert atmosphere to form a char; communicating the char to from a powder; heating the powder to form the plurality of non-crystalline hydrophobic silica particles.
