Rare Earth Elements
Rare Earth Elements, due to their geochemical properties, are typically dispersed and not often found in concentrated and economically exploitable forms. The few economically exploitable deposits are known as Rare Earth Minerals.

Rare Earth Metals
Commonly used metals:
Name: Aluminum–a.k.a.Aluminium
Atomic Number: 13
Symbol: Al
History: In 1761, Guyton de Morveau suggested calling the base alum alumine. In 1808, Humphry Davy identified the existence of a metal base of alum, which he at first termed aluminum and later aluminum.
Applications/Uses: Aluminum and its alloys are used because they are easy to form, readily available, inexpensive, and recyclable.
Name: Copper
Atomic Number: 29
Symbol: Cu
History: Copper and its alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as cyprium (metal of Cyprus), later shortened to cuprum.
Applications/Uses: Copper and copper alloys have a number of properties that make them useful, including high electrical and thermal conductivity, high ductility, and good corrosion resistance.
- Yttrium Name: Yttrium
Atomic Number: 39
Symbol: Y
History: It has been named after the village of Ytterby, Sweden, where the first rare earth ore was discovered.
Applications/Uses: Yttrium-aluminium garnet (YAG) laser, yttrium vanadate (YVO4) as host for europium in TV red phosphor, YBCO high-temperature superconductors, yttrium iron garnet (YIG) microwave filters.
