摘要： PROBLEM TO BE SOLVED: To simply and continuously activate the surface of spherical silica while maintaining the grain size and shape of spherical silica and to improve the adhesion property of the silica to a matrix resin by treating the spherical silicon powder in a fast gas flow which can maintain the grain shape of the powder to use collision among the powder particles. SOLUTION: The surface of a silica powder is fired or fused by heating in the flame of an inflammable gas, plasma flame, arc fusing furnace, high frequency furnace or by a laser method to obtain a spherical silica powder. The obtd. powder is introduced with an accelerating gas flow through a supply nozzle into a pulverizing room where the powder is reserved for a specified time at a fast velocity in an atmosphere of 0.5 to 2.5 kg/cm flow pressure containing the silica powder so as to treat the powder by using the collision among the silica powder particles. Then the powder with the gas flow is carried to the outside of the pulverizing room and only the powder is collected by a bag filter or the like. Thereby, the original grain size and shape of the powder can be almost maintained and the adhesion property of the powder with a resin can be improved without decreasing the fluidity as an inorg. filler for a resin.
