It is formed as a byproduct of the Solvay process, also called ammonia-soda process to make sodium carbonate from calcium carbonate and sodium chloride. It is also prepared by dissolving calcium carbonate or calcium oxide in hydrochloric acid. It is used chiefly for dust control on unpaved roads and as a roadway deicer. Other uses are waste water treatment, brine refrigeration systems, tire weighting, concrete acceleration and as a calcium source in chemical processing.
