Description
A hygroscopic substance that will remove water vapor from the air. Desiccants are used as drying agents. Some desiccants are chemically inert and may be dried in an oven and reused, such as silica gel. Other desiccants are react with water; these require special handling techniques.
Examples are Activated carbon, aerogel, Activated alumina, Calcium chloride, Calcium oxide, Calcium sulfate, Clay, molecular sieves, Potassium carbonate, Potassium hydroxide, Rice, Silica gel, Sodium, Sodium chlorate, Sodium chloride, Sodium hydroxide, Sodium sulfate, Sucrose and Zinc chloride.
Synonyms and Related Terms
