A colloid is a stable dispersion of particles - particles that are small enough that gravity doesn't cause them to settle, but large enough not to pass through a membrane and allow other molecules and ions to pass freely. A dust mask with particle filtering capability should be worn if high concentrations of dust are generated in the work environment. During the synthesis process, minute droplets of SiO2 initially aggregate into so-called nuclides, which combine stochastically into even larger particles, facilitated by weak physical interactions such as van der Waals forces. Any standard silica grade can be used, although grades with much larger specific surface areas, such as Evoniks AEROSIL 300 Pharma are the most recommended.
