Thallium, a soft, bluish-gray, malleable heavy metal, was discovered by Sir William Crookes in 1861 while he was making spectroscopic determinations for tellurium on residues from a sulfuric acid plant. Although the metal is reasonably abundant in the Earth's crust at a concentration estimated to be about 0.7 part per million, it exists mostly in association …
Due to the absence of the elements or very low determined concentration, tellurium was not included in the exposure assessment and in the general risk assessment. Thallium: In the case of thallium, it is known that its salts can cause a wide spectrum of adverse effects in humans and animals, and thallium is considered a cumulative poison …
Tantalum, Ta. Tantalum (Ta) is a dense, hard, grayish-blue metal that is highly corrosion-resistant. It is part of the refractory metals group, which are characterized by their high melting points and resistance to wear, corrosion, and deformation. Due to its inertness, tantalum is often used in the manufacture of medical implants and surgical ...
Thallium bromide (TlBr) is a crystalline compound with interesting properties that make it suitable for radiation detection applications.

Tellurium, Te Tellurium (Te) is a relatively rare, brittle, and silver-white metalloid with a crystalline structure. It is found naturally in the Earth's crust and is primarily obtained as a byproduct of the refining of copper ores. Tellurium has the unique property of being more conductive in certain directions, which can be valuable in ...
Tellurium: description. Crystalline tellurium has a silvery-white appearance, and exhibits a metallic lustre when pure (see above). It is brittle and easily pulverised. Tellurium is a p-type semiconductor, and shows …
Thallium bromide-iodide crystals have also been used in infrared detectors. The addition of metals like thallium to glass can also reduce its melting point to as low as 150 degrees centigrade. As such low-melting point glasses do not shatter like normal glasses, they are particularly useful for the manufacture of electronic parts.

Tellurium is a rare, silvery-white, brittle, lustrous metalloid. It burns in air with a greenish-blue flame and forms white tellurium dioxide (TeO 2 ). When present in compounds, tellurium exists mostly in the oxidation state IV and VI. Tellurium is a semiconductor material and is slightly photosensitive.
