IYPT 2019 Elements 073: Tantalum: Electronics and implants

Element 73 in our International Year of the Periodic Table series is tantalum. Tantalum is used in electrical components in phones and computers; it’s also used in dental and surgical instruments and implants.

Tantalum’s major use is in electrical components for mobile phones, tablets, computers, and other devices. In particular, it’s used for capacitors and resistors.

Tantalum is also used in dental and surgical instruments and implants. It’s useful for this purpose as it doesn’t trigger an immune response in the body and resists attack by bodily fluids.

Tantalum is also used in a number of different alloys with other metals. These alloys tend to be strong and have high melting points, giving them uses in turbine blades, jet engine components, and more.
