About this item

IUPAC name	tellurium
canonical smiles	[Te]
inchi	InChI=1S/Te
inchi key	PORWMNRCUJJQNO-UHFFFAOYSA-N
molecular formula	Te
synonyms	13494-80-9 Te Tellurium Tellurium, metallic Tellurium, elemental
Compound Description	Grayish-white, lustrous, brittle, crystalline solid; dark-gray to brown, amorphous powder with metallic characteristics. Used as a coloring agent in chinaware, porcelains, enamels, glass; producing black finish on silverware; semiconductor devices and research; manufacturing special alloys of marked electrical resistance. Improves mechanical properties of lead; powerful carbide stabilizer in cast iron, tellurium vapor in "daylight" lamps, vulcanization of rubber. Blasting caps. Semiconductor research. Tellurium atom is a chalcogen and a metalloid atom. Tellurium is a natural product found in Paris polyphylla var. chinensis with data available. Tellurium is an element with atomic symbol Te, atomic number 52, and atomic weight 127.6. Tellurium is a mineral with formula of Te. The IMA symbol is Te. An element that is a member of the chalcogen family. It has the atomic symbol Te, atomic number 52, and atomic weight 127.60. It has been used as a coloring agent and in the manufacture of electrical equipment. Exposure may cause nausea, vomiting, and CNS depression.

hazard statements	H301 (17.17%): Toxic if swallowed [Danger Acute toxicity, oral] H317 (45.66%): May cause an allergic skin reaction [Warning Sensitization, Skin] H319 (37.37%): Causes serious eye irritation [Warning Serious eye damage/eye irritation] H332 (65.66%): Harmful if inhaled [Warning Acute toxicity, inhalation] H335 (37.17%): May cause respiratory irritation [Warning Specific target organ toxicity, single exposure; Respiratory tract irritation] H360 (24.85%): May damage fertility or the unborn child [Danger Reproductive toxicity] H360Df (28.48%): May damage the unborn child; Suspected of damaging fertility [Danger Reproductive toxicity] H362 (33.13%): May cause harm to breast-fed children [Reproductive toxicity, effects on or via lactation] H413 (45.45%): May cause long lasting harmful effects to aquatic life [Hazardous to the aquatic environment, long-term hazard]
hazards summary	The TLV excludes the compound hydrogen telluride (H2Te). Garlic odor of the breath, urine, and sweat are signs of tellurium absorption. Foundry workers exposed to 0.01-0.1 mg/m3 with a peak of 0.74 mg/m3 complained of metallic taste, somnolence, and garlic odor. Signs of tellurium poisoning in experimental animals include pneumonitis, hemolytic anemia, hematuria, paralysis, convulsions, and coma. In 2 cases of human poisoning after instillation of 2 grams of sodium tellurite by ureteral catheter, the patients suffered cyanosis, stupor, and signs of liver injury and died 6 hours after the accident. There have not been any reports of serious occupational illnesses or deaths. Causes damage to the nervous system, liver, kidneys, and heart in animal experiments. In high-dose animal studies, tellurium produces birth defects (hydrocephalus). Tellurium is a hepatotoxic agent. Tellurium is a skin and respiratory tract irritant. It can have effects on the CNS and liver. See Tellurium hexafluoride.
