Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as
tantalium, its name comes from Tantalus, a hero from Greek mythology. Tantalum (Ta) is a
dark blue-gray metal that is very heavy, ductile, and hard and has high corrosion
resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C
and can only be dissolved with hydrofluoric acid. It has the fourth-highest melting
point of all metals and is able to form extremely thin and protective oxide layers for
high-quality capacitors, making it an excellent material for tubes. It is part of the
refractory metals group, which are widely used as minor components in alloys
The chemical inertness of tantalum makes it a valuable substance for laboratory
equipment and a substitute for platinum. Tantalum is also used for medical implants and
bone repair. Its main use today is in tantalum capacitors in electronic equipment such
as mobile phones, DVD players, video game systems and computers. Tantalum, always
together with the chemically similar niobium, occurs in the minerals tantalite,
columbite and coltan (a mix of columbite and tantalite). Tantalum is a rare metal,
comprising just 8×10−9% of the universe, making it fifteen times less abundant in the
universe than gold (which makes up 6×10−8%). Tantalum also comprises just 1.5×10−4% of
the earth’s crust, making it more abundant than other metals in the sixth period, such
as rhenium (abundance 2.6×10−7%), osmium (abundance 1.8×10−7%), or iridium (abundance
4×10−8%), but not as abundant as barium (abundance 3.4×10−2%).
