calcium chloride

Calcium chloride is an ionic compound of calcium and chlorine. It is highly soluble in water and it is deliquescent. It is a salt that is solid at room temperature, and it behaves as a typical ionic halide. It has several common applications 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. Millions of tons of calcium chloride are made each year in the US alone, and in 1990 the bulk price there was $182 per ton. In order to promote and strength the calcium industry the Chinese government encourages various calcium manufactory enterprise to advance the technology scientifically, to purchase patent, absorb science and technology stock ownership, cooperation and other measures, develops the new product and so on., the calcium carbonate product has covered from common level, superfine level, tiny level to nanometer level at present, it also develops to edible specialized and papermaking calcium product. the division of labor of various calcium enterprise is clear and cooperation is closely, the calcium carbonate profession association has established, The government determined that the characteristic industry development will be given special support policy , and issue certain opinions to promote calcium industry development, it is claimed that the government will support the land, financing, preferential benefit reward policy, the technological transformation fund and so on, there is a leading group service for calcium industry all the time.
