Introduction
•
Iron and steels are the most important construction
materials.
•
Their production is based on the reduction of iron
oxides, the removal of impurities and the addition of carbon and alloying
metals such as Cr, Mn and Ni.
•
Some compounds are manufactured for special purposes
such as TiO for the pigment industry and MnO2 for use in dry battery
cells.
•
The battery industry also requires Zn and Ni/Cd.
•
The elements of Group 11 are still worthy of being
called the coinage metals, although Ag and Au are restricted to collection
items and the contemporary UK ‘copper’ coins are copper-coated steel.
•
The ‘silver’ UK coins are a Cu/Ni alloy.
Many of the metals
and/or their compounds are essential catalysts in the chemical industry. V2O5
catalyses the oxidation of SO2 in the manufacture of sulphuric acid.
