  • SURFACE-TREATED SOL-GEL SILICA AND METHOD FOR PRODUCING SAME
    Publication number: 20200199371
    Abstract: This surface-treated sol-gel silica is characterized by containing sol-gel silica having an average particle size of 0.05 ?m or more and 2.0 ?m or less as measured by laser diffraction scattering and a surface treatment agent on the surface of the sol-gel silica. In a dispersion produced by dispersing 5 mass % of the sol-gel silica in ethanol by emitting ultrasonic waves at 40W for 10 minutes, the content of particles with particle sizes of 5 ?m or more is 10 ppm or less in a particle number size distribution obtained by a Coulter counter method.
