A layer of metal about 50 micrometres thick is deposited onto a porous carbon skeleton to create a rigid material that has a similar structure to bone itself, meaning that once the new joint is in the body, the patient's bone and soft tissue can bond with and grow into the implant. Because tantalum can be used to coat other metals with a very thin layer, a high capacitance can be achieved in a small volume. What makes the elements ideal for phones, and other dinky electronic devices, such as handheld game consoles, laptops and digital cameras, is that the metal is extremely good at conducting both heat and electricity, meaning that it can be used in small components that don't crack up under pressure.
