Tellurium . A brittle, agilely toxic, rare, silver-white metalloid which looks agnate to tin, tellurium is chemically accompanying to selenium and sulfur. It is occasionally begin in built-in form, as basal crystals. Tellurium is far added accepted in the cosmos as a accomplished than it is on Earth. Its astute aberration in the Earth's crust, commensurable to that of platinum, is partly due to its top diminutive number, but aswell due to its accumulation of a airy hydride which acquired the aspect to be absent to amplitude as a gas during the hot nebular accumulation of the planet.
Commercially, the primary use of tellurium is in alloys, foremost in animate and chestnut to advance machinability. Applications in solar panels and as a semiconductor actual aswell absorb a ample atom of tellurium production.
Tellurium has no biological function, although fungi can absorb it in abode of sulfur and selenium into amino acids such as tellurocysteine and telluromethionine. In humans, tellurium is partly metabolized into dimethyl telluride, (CH3)2Te, a gas with a garlic-like odor which is exhaled in the animation of victims of tellurium toxicity or exposure.
