Did you know?
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. WebSilica gel is an amorphous silicon dioxide, which in comparison to clay, can adsorb a higher amount of moisture. Due to its high adsorption capacity in relation to its own weight, silica gel is used particularly in compact products as a desiccant in the pharmaceutical and diagnostics sectors and in the food industry.. Silica gel adsorbs very little water vapor at …
