plain

Plain sicastar® particles have a hydrophilic surface with terminal Si-OH-groups without any additional functional groups on the surface. The plain particles are available in the size range of 10 nm to 20 µm and are supplied in water or as powder on request. The nonporous sicastar® particles have small monomodal size distributions with polydispersity indices < 0.2. The larger porous sicastar® particles have broader size distributions of 3 ± 0.5 µm, 4 ± 0.5 µm, 5 ± 0.8 µm, 10 ± 2.5 µm, 15 ± 4 µm and 20 ± 11.5 µm.
The particles are supplied in water without any surfactants.
