Tellurium (Te)

Tellurium (Te)

Discovered in 1782 and isolated in 1798, tellurium in its crystalline form is brittle and silvery-white with a metallic luster.

More often found as the telluride of gold (calaverite) or combined with other metals, it can be found naturally. Natural tellurium consists of eight isotopes, and thirty other isotopes are known.

Tellurium is a p-type semiconductor, exhibits varying conductivity based on atom alignment, and gains conductivity when exposed to light. It produces greenish-blue flames. Tellurium and its compounds are likely toxic.

Tellurium improves copper and stainless-steel handling, decreases corrosion, and increases the strength and hardness of lead.
