Calcium Chloride

Chemical Description

Calcium chloride is a member of the salt family of elements and is made up of calcium and chlorine. It is a white, odorless, hygroscopic powder. It is supplied in many different forms (pellet, flake, or granules) depending on the requirements of the application. When dissolved in water it produces a clear, colorless solution.

Common Industrial Uses of Calcium Chloride

Calcium chloride is widely used in a broad range of applications and industries. It is a premium salt that is used for ice control, road stabilization, dust suppression, and in oilfield applications. As a hygroscopic compound, calcium chloride is an excellent desiccant for removing dissolved water in liquids and is suitable for use in food packaging to increase dryness and prevent spoiling.

The oil and gas industry uses calcium chloride to increase the density of solids-free brines and to inhibit the swelling clays in the water phase of invert emulsion drilling fluids. Calcium chloride is widely used as an additive in plastics, wastewater treatment plants, and blast furnaces to improve processes and characteristics.

Used as an agent to lower the freezing point of water, calcium chloride is very effective for preventing ice formation on road surfaces and as use as a deicer. It also hardens swimming pool water by acting as a pH buffer, which reduces the erosion of pool concrete.

Safety Considerations

Because calcium chloride is a desiccant, it can have severe drying effects on the body and skin. It is acutely toxic and is a skin and eye irritant. If ingested in concentrated solutions or solids, gastrointestinal irritation or ulceration could occur.
