Mercury intrusion experiments with silica spheres

Mercury Intrusion Experiments with Silica Spheres. These silica spheres (S980 G1.7 from Shell) were not examined in the same detail as were the other silica samples, but the photographs are included because they illustrate the effect of mercury intrusion on the integrity of the solid. These particular spheres have a typical pore volume of 1 cm3/g and a pore diameter of 60 nm. The particles are also much larger than the Sorbsil materials (1.7 mm in diameter, compared to 40 to 60 pm for the Sorbsil materials).
