Silica gel is one of a number of available dessicants, each with its
own uses. It is a form of silicon dioxide (quartz), one of the least
reactive substances known. Silica gel is often used in electronic
equipment to combat humidity.
Another class of dessicants comprises molecular sieves such as
zeolites, which are used in some vacuum pumps. These are generally
non-reactive, and some may be suitable for use in electronic equipment.
Calcium sulfate and calcium chloride are sometimes used as dessicants
in electronic equipment, but are more reactive and may be more likely
to cause problems than silica gel or zeolites.
