Nov 15, 2020The contribution of molecular diffusivity to the D app /R p 2 values was minor because molecular diffusion is too rapid to control N 2 O adsorption on silica gel. Furthermore, the D app /R p 2 values of silica gel particles (0.2-0.5 mm) calculated from the two different methods (1st and 3rd) were in the same order of magnitude (1 × 10 −2).

Silica gel was classified according to size, and denoted as "silica gel pellets (>4 mm)" and "silica gel pellets (2 mm)"; the values in parentheses indicate the particle size range of each group. In addition, grinding silica gel was prepared by crushing the silica gel pellets and sieving the particle through a range of mesh sizes.

Many materials used to fabricate products, such as stone benchtops, contain varying levels of crystalline silica. The cutting, grinding, trimming, sanding or polishing of these materials produces very small particles of dust, including RCS. If inhaled, RCS can cause serious and fatal diseases, including silicosis and auto- immune diseases.
