Abstract: A filler for resinous composition is contained and used in resinous composition constituting electronic packaging material for electronic device, and includes: a filler ingredient including a crystalline siliceous material with a crystal structure made of at least one member selected from the group consisting of type FAU, type FER, type LTA, type MFI and type CHA, and/or type MWW, wherein: the filler ingredient is free of any activity when evaluated by an “NH3-TPD” method; and includes the crystalline siliceous material in an amount falling in a range allowing the filler ingredient to exhibit a negative thermal expansion coefficient. The filler ingredient may further be free of a surface in which silver, copper, zinc, mercury, tin, lead, bismuth, cadmium, chromium, cobalt and nickel are exposed.

Abstract: A composite material includes a resinous particulate material, and an inorganic particulate material having a particle diameter being smaller than that of the resinous particulate material, fused welded onto a surface of the resinous particulate material, formed of an inorganic oxide, and including OH groups generated by fuse welding in the surface. The composite particulate material exhibits a degree of sphericity of 0.8 or more, and a has volumetric average particle diameter of from 0.1 to 100 μm.

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 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.
