Figure 3.4 potential SiO2 surface groups of hydrophilic silicas [140] AEROSIL R 972 became the first hydrophobic silica to be manufactured on an industrial scale in 1962. Further hydrophobic AEROSIL grades are now available, produced by similar industrial-scale methods using corresponding silanes. Figure 3.5 provides a sampling of the many hydrophobic grades available and highlights the difference between them and hydrophilic AEROSIL grades according to the schematically represented surface groups. All hydrophobic AEROSIL types carry the suffix “R“ to indicate their water-repellent character.

The reference [140] might be a previous edition of the source documented here. The figures are therefore referenced appropriately, the text between the figures, however, is not referenced at all. |
