HISTORY,
BACKGROUND & USES:
Discovered in 1875 by Paul-Émile Lecoq de Boisbaudran. Gallium liquifies just above room temperature. It is silvery
white, and soft enough to be cut with a knife. It may take on
a bluish tinge due to superficial oxidation. Gallium expands when
solidified and supercools readily, sustaining its liquid form
as low as 0 °C. It can be used as a coating for optical mirrors,
as a liquid seal in strongly heated apparatus, and a substitute
for mercury in ultraviolet lamps.
