The primary particles of fumed silica leaving the burner are in a molten state; therefore, on collision they are able to coalesce, forming bigger particles (aggregates). During cooling down and collection, these aggregates produce agglomerates. These agglomerates can be disintegrated on mixing during...
Particle size distributionShear thickening ratioWe present a systematic rheological study on the fumed silica suspensions to understand the effect of particle and fluid parameters on the critical shear rate and shear thickening ratio. It was observed that removal of air bubbles and water contamination ...
a crosslinking agent; bimodal particle size distribution of nano-scale particles; smaller particles consist of fumed silica; larger particles consist of spherical silica; low viscosity in the uncured state and low coefficient of thermal expansion in the cured state; multilayer printed circuit boardsUS...
Preparation from the gas phase is limited to only a handful of inorganic particles with volatile precursors, such as fumed silica and titania [39]. Perhaps the most common gas-phase approach to nanoparticle formation is the aerosol process [31,40], in which a super-saturated vapor of the pre...
It is another object of the invention to provide an apparatus for densifying of fumed silica powder materials having apparent densities of no greater than about 25 kg/m3 wherein the apparent density of the densified fumed silica product is greater than about 100 kg/m3 and wherein the densified...
Spherical nanosilica particles of three different sizes (100, 300, and 500 nm) as well as fumed silica particles of four different specific surface areas (Aerosil A-90, A-130, A-150, and A-200), respectively, were used in this study. The test samples were prepared by dispersing ...
