History of Technetium
Technetium was reported to have been discovered in 1925; at the time it was named Masurium. But it was actually discovered by C. Perrier and Emilio Gino Serge in Italy in 1937. It was found in a sample of molybdenum bombarded by deuterons. A deuteron is the nucleus of a deuterium atom, consisting of a proton and a neutron. Technetium was the first element to be produced artificially and all its isotopes are radioactive, like it.
USES OF TECHNETIUM
- Frist Technetium is found in ammonium pertechnate (NH4TcO4), which is a special corrosion inhibitor for steel.
- Also as a superconductor at 11K or below and it is used for tracker work (which is used in radioactive tracers)
- Finally Technetium is medical imaging agents (such as x-rays), this is where we find the element the most.
