Tinclavic
From Tardis Wiki, the free Doctor Who reference
Tinclavic was a malleable mineral mined on the planet Raaga. It was primarily used by the Hakolian who used Terileptil prisoners to mine the mineral. (TV: The Visitation)
In 1984, Sir George Hutchinson had a small ball of tinclavic with which he constantly toyed during a re-enactment of the Battle of Little Hodcombe. (TV: The Awakening)
Tinclavic was also used in the construction of several spacecraft, including the I's spacecraft (which was actually the shell of a creature which secreted it naturally) and the Time Lords' Time Station (in which triple-bonded polysium was also used). (PROSE: Seeing I, AUDIO: Neverland)
