摘要： This invention provides flame-generated fine silica particles having an average particle size of 0.05 to 1 μm, wherein a fractal structure parameter α1 at length scales ranging from 50 nm to 150 nm and a fractal structure parameter α2 at length scales ranging from 150 nm to 353 nm satisfy the following formulas (1) and (2): −0.0068S+2.548≦α1≦−0.0068S+3.748 (1) −0.0011S+1.158≦α2≦−0.0011S+2.058 (2) wherein S is a BET specific surface area (m2/g) of the fine silica particles, in the measurement of small-angle X-ray scattering. When used as a filler for a semiconductor-encapsulation resin or when used as a filler for a polishing agent or for a coating layer for ink jet papers, the fine silica particles are available at high content without substantial enhancement of the viscosity. Besides, when used as a filler for the resin, the fine silica particles improve the strength of the molding compound. Furthermore, when used as a toner additive for electrophotography, the fine silica particles improve the free-flow property of the toner without removal from the toner surfaces.

摘要： Fine dry silica particles are produced by combustion by using a burner of a multiple-pipe structure, feeding a mixed gas of a gas of a siloxane compound without containing halogen in the molecules thereof and an oxygen gas at a ratio of 0.3 to 1.5 into the center pipe of a burner, and feeding a combustible gas into the first annular pipe on the outer side of the center pipe of the burner. The fine dry silica particles has a BET specific surface area of 20 to 55 m2/g, and wherein the water suspension containing the fine silica particles at a concentration of 1.5% by weight has an optical absorbance τ for the light of a wavelength of 700 nm satisfying the following formula (1): τ≦240S−1.4−0.07 (1) wherein S is the BET specific surface area (m2/g) of the fine dry silica particles. The fine dry silica particles do not almost contain coarse particles or aggregated particles, have a sharpe grain size distribution, excellently disperse in the resins, suppress a rise in the viscosity when highly filled, and impart sufficiently large strength to the resin compound.
