Metallurgy
Metals: Metals play a very vital role in our daily life. Today we know about eighty metals. Let us now study the metals in detail.
Physical Properties: All metals are solid at room temperature, except mercury, which is a liquid. Most of the metals are hard, and have high melting and boiling points. Metals are malleable i.e. they can be beaten into sheets. Gold and silver are the best malleable metals and these can be hammered into foils. Most of the metals are ductile i.e. they can be drawn into thin wires. All metals are good conductors of heat; silver is the best and lead (Pb) is the poorest conductor of heat among metals. Metals also show high electrical conductivity. The best conducts of electricity are silver, copper, gold, aluminium and tungsten.
Metallurgy: Some metals are not found in the free or native state, but are found in nature in combined states. The natural materials in which metals or their compounds occur in the earth are called minerals. Those minerals from which the metals are produced profitably are called mineral ores. Extraction of metals from their ores and refining them for use is called metallurgy.
