Uses of Hydrogen in Industry Features The Chemical Engineer

Atomic hydrogen welding AHW is an arc welding process that uses an arc between two metal tungsten electrodes in a shielding atmosphere of hydrogen, and can be used to weld refractory metals and tungsten. Hydrogen as a coolant. Many modern large electrical generators use hydrogen gas as a rotor coolant at a pressure of around 4 bar.

Coltan Wikipedia

Coltan short for columbitetantalites and known industrially as tantalite is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobiumdominant mineral in coltan is columbite after niobium 39s original American name columbium , and the tantalumdominant mineral is the tantalite.
