Abstract: A production method for an electronic material filler includes: a preparation step of preparing a silica particle material produced by a dry method; and a first surface treatment step of performing surface treatment on the silica particle material with a silane compound having a vinyl group, a phenyl group, a phenylamino group, an alkyl group having four or more carbon atoms, a methacryl group, or an epoxy group, to obtain a first surface treatment-processed particle material. After the silica particle material is produced by the dry method, the silica particle material is not brought into contact with liquid water, and has a particle diameter of 100 nm to 600 nm or a specific surface area of 5 m2/g to 35 m2/g.

Abstract: A plasticizer composition to be used in a transparent resin for optics, wherein the plasticizer composition includes: a composite aggregated particulate material; and a liquid plasticizer having dispersed therein the composite aggregated particulate material. The composite aggregated particulate material includes an inorganic aggregate material being a granular material formed of aggregates of an inorganic particulate material formed of silica having a specific surface area particle diameter of not less than 0.8 nm and not greater than 80 nm, and an organic coating material formed of an organic matter coating a surface of the inorganic aggregate material. A mass of the organic coating material is not less than 0.8% and not greater than 80% with respect to a sum of a mass of the inorganic aggregate material and a mass of the organic coating material. Both mechanical properties and optical properties are realized by mixing the plasticizer composition.

Abstract: A modified metal oxide particle material includes: a metal oxide particle material having, on a surface thereof, a functional group other than a phenyl group; and a modifying material formed of a silicon-containing compound having a phenyl group. The modifying material is adhered to the surface of the metal oxide particle material. When the modified metal oxide particle material is washed with methyl ethyl ketone, a ratio (C/H) of a carbon content C (% by mass) to a surface area H (m2) per 1 g is 0.05 or less, after the washing. The ratio (C/H) is reduced by 0.1 or more, and the modifying material is removed by 50% or more by mass, after the washing compared with before the washing.

Abstract: A particle material that has high dispersibility in a dispersion medium such as toluene having high hydrophobicity, and a slurry composition in which the particle material is used, are provided for solving the problem. A surface-modified particle material of the present invention includes: a particle material formed of an inorganic material; and a surface treatment agent formed of a silane compound having a first functional group that has any of C, N, and O atoms away over five or more atoms from Si to which an alkoxide is bound, the surface treatment agent allowing surface treatment of the particle material in such an amount that a degree of hydrophobicity becomes not less than 30%. Dispersibility is enhanced also in a dispersion medium having high hydrophobicity in a case where a functional group having a predetermined structure is introduced so as to impart predetermined or higher hydrophobicity.
