Inorganic chemicals

Ammonia is an example of a large volume inorganic chemical. Ammonia's major use is as a nitrogen source in fertilizers where it is used to produce derivatives including ammonium nitrate, urea, ammonium phosphates and ammonium sulphate. Ammonia can also be used in combination with phosphate rock and potassium to form N-P-K compound fertilizers. Ammonia is also used as intermediate in the production of nylons, acrylonitrile for fibres and plastics, isocyanates for polyurethanes, hydrazine and explosives.

Chlorine is used in the manufacture of many different products including polyvinyl chloride (PVC), organic and inorganic chemicals, agrochemicals and pharmaceuticals as well as chemicals for water treatment and sterilisation.

Co-produced with chlorine is caustic soda which is a versatile alkali. Its main uses are in the manufacture of pulp and paper, alumina, soap and detergents, petroleum products and chemical production. Other applications include water treatment, food, textiles, metal processing, mining, glass making and others.
