titleOfInvention | Dry-process fine silica particle |
abstract | 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 m 2 /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 ≦ 240 S - 1.4 - 0.07 nwherein S is the BET specific surface area (m 2 /g) of the fine dry silica particles. nThe 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. |
