So DIU M THE element sodium, a soft silvery and highly reactive metal, is never found free in nature but is widely distri- buted in the form of compounds. The best known of these is sodium chloride or common salt-the raw material from which sodium and many of its compounds are produced commercially. Salt occurs abundantly in sea water, but industrial supplies are obtained mainly from deposits of rock salt left in the earth'$ crust by the evaporation of prehistoric seas. Apart from the use of sodium in sodium vapour lamps, a familiar form of street lighting, the element itself is little known outside the chemical industry. ICI produces sodium for a number of industrial processes; and uses it in large quantities to make sodium cyanide-for gold extraction, casehardening and electroplating-and sodium peroxide for textile bleaching: Other sodium compounds pro- duced by ICI: include salt, and the important heavy chemicals caustic soda and soda ash; Caustic soda is essential to the manufacture of soap, paper, textiles, explosives and dyestuffs_ Soda ash is used in SO many different industrial products and processes that it is almost as vital to a nation S industries a5 coal or iron.
