Calcium chloride


Other commercial names

Calcium(II) chloride, calcium dichloride, E509


Chemical formula



Physical properties

It is solid at room temperature but there is also a solution. Calcium chloride is a white crystalline material. Its appearance is in the form of grains, lumps or flakes


Product type





This compound absorbs highly moisture and is recognized as a desiccant (drying agent). This salt is soluble in water and releases heat during the dissolution in water, which is associated with high enthalpy dissolution of this material. It is stable and non-flammable.

Production Process


calcium chloride is obtained by 3 methods: 1- with the help of hydrochloric acid and limestone. 2- by purification of brine.3- from limestone as a by-product of the Solvay process




This material should be kept in air-tight and moisture-proof containers. It is necessary to keep the containers in a dry, cool, and air-conditioned place. Do not store above 30 ° C.
