Product Details
Calcium chloride dihydrate (CaCl2﹒2H2O) is the hydrate form of calcium chloride. Calcium chloride is an inorganic compound consisting of calcium and chloride. It has various kinds of applications. For example, it can be used as a desiccant due to its high hygroscopicity; used for the deicing and dust control; for road surfacing; as brine for refrigeration plants, ice and cement; increasing the water hardness in the swimming pools; as a food additives; increasing the cell membrane permeability to facilitate the genetic transformaleic-anhydride.html">mation of cells; for the treatment of hypocalcemia in which the body requires a prompt increase in blood plasma calcium levels, For its production, it can be either produced directly from limestone or produced by the Solvary process as the by-product. In addition, it can also be obtained by purification from brine.
