Such nanoparticles may be made by (1) subjecting a mesoporous silica starting material (e.g., SBA-16 or KIT-6) to a pressure of less than about 20 GPa (e.g., about 12 GPa); (2) heating the mesoporous silica starting material while under pressure to an elevated temperature of less than about 1000° C. (e.g., a temperature of between about 300° C. and about 400° C.); and thereafter isolating the nanoparticles. The nanoparticles may be used in a work tool that is configured and adapted for cutting, drilling, abrading, polishing, machining, or grinding, among other uses.

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.
