Tantalum is a chemical element with symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a character from Greek mythology.Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. 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.
Health effects of tantalum
May be harmful by inhalation, ingestion or skin absorption. Causes eye & skin irritation. Material is irritating to mucous membranes & upper respiratory tract.
There are no reports of adverse health effects in industrially exposed workers. Massive doses of tantalum given by intratracheal route to rats have produced respiratory tract lesions. In contact with tissue, metallic tantalum is inert.
Environmental effects of tantalum
Do not allow material to be released to the environment without proper governmental permits.
Isolate runoff of tantalum oxide to prevent environmental pollution.
