Barium was discovered by Sir Humphrey Davy at 1808 in England. Origin of name: from the Greek word barys meaning heavy Baryta (barium oxide, BaO) was distinguished from lime (calcium oxide, CaO) by Scheele in 1774.
Barium was identified as a new element in 1774, but not reduced to a metal until 1808 with the advent of electrolysis. Barium has only a few industrial applications. The metal has been historically used as a getter for vacuum tubes.It is a component of YBCO (high-temperature superconductors) and electroceramics, and is added to steel and cast iron to reduce the size of carbon grains within the microstructure of the metal.arium has only a few industrial applications.
