Description

Thallium is a poisonous, bluish-grey metal that tarnishes quickly in air. Today, thallium doesn't have too many applications due to its toxicity. The metal itself has no commercial value, and very few of its compounds do. Among these, thallium sulphide and oxysulphide are used to manufacture high quality photovoltaic cells, the latter of which has the particularity of being very sensitive to infrared light.
