Top 12 interesting facts about Thallium
Thallium was discovered in 1861 by Sir William Crookes. Its name derives from the Greek word "thallos" which means "young shoot".
Thallium's melting point is at 303.5 C (576.65 K, 578.3 F) and its boiling point is at 1457.0 C (1730.15 K, 2654.6 F).
Thallium has a gray color and it is a soft and ductile metal.
Thallium tarnishes when exposed to air and reacts with water.
Thallium is not found freely in nature.
Thallium is produced as a byproduct of refining sulfide ores.
Thallium has two stable isotopes: 203-Tl and 205-Tl.
Thallium is mainly used in electronic industry for photo-resistors production and for infrared and gamma radiation detection devices.
Thallium is used in research and production of high-temperature superconducting materials.
Thallium is also used in optics industry for producing glasses with a high index of refraction and glasses with a high density.
Thallium is used in different niche applications such as nuclear medicine, thermometers and low-temperature switches (mercury-thallium alloy), in anodes of seawater batteries, and few others.
Thallium and its compounds are very toxic.
