Calcium chloride is made by ionic compound of calcium and chlorine. This compound is easy to dissolve in water and it is deliquescence. It states as a solid at room temperature. It also behaves as a typical ionic halide. It is using for commom things for our enviroment; such as brine for refrigeration plants, ice and dust control on roads, and in cement. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly-sealed containers.

Properties
Calcium chloride (CaCl2), in the liquid form, is a highly soluble hygroscopic solution that is also exothermic. Its ability to draw in moisture from its surroundings, resist evaporation, and release heat in a chemical reaction makes it the perfect substance for road construction and maintenance, including ice and dust control and base stabilization. As proven experts, Ward Chemical can produce various concentrations of liquid calcium chloride. Simply tell us your needs and we can customize a solution. [2]
