Abstract: Provided is a method for manufacturing a spherical particle material in which the particle size distribution is easily controlled. This method has: a granulation step of granulating a raw particle material formed of an inorganic material having a D50 of not larger than 5 μm to form a granulated body; and a spherizing step of heating and melting the granulated body to form the spherical particle material having a D50 larger than a D50 of the raw particle material. A melting method is used as a basic method for manufacturing the spherical particle material having a necessary particle size distribution. The granulated body is used to manufacture the spherical particle material having the necessary particle size distribution by the melting method.

Abstract: A particulate material is mainly composed of alumina, has a volume average particle diameter of from 70 to 200 μm, has a degree of sphericity of from 0.89 or more to less than 0.99, has a degree of alfa-aluminization of from 40 to 85%, and produces a result of 0.017 g or less in an abrasion test for equipment.

Abstract: A silicone-coated filler comprises: a particulate material mainly composed of an inorganic oxide formed by oxidizing a predetermined element; a first silicone structure bonded to a surface of the particulate material by way of a “-‘the predetermined element’-OSi—” structure; and a second silicone structure including a cross-linking structure with a carbon-carbon structure directly bonded to a silicon atom of the first silicone structure, and a polysiloxane structure bonded to the cross-linking structure.
