WebSilica gels are classified into three types: regular, intermediate, and low density gels. Regular density silica gel is prepared in an acid medium and has a high surface area (e.g., 750 m 2 g −1 ). Intermediate and low density silica gels have low surface areas (300–350 and 100–200 m 2 g −1, respectively). WebSilica gel is extremely efficient at temperatures below 77°F (25°C) (see Figures 1 and 2), but will lose some of its adsorbing capacity as temperatures begin to rise, much like clay (Figure 3). Much of silica gel's popularity is due to its non-corrosive, nontoxic nature and its having received US government approval for use in food and drug packaging.
