Appearance
A semi-metal usually acquired as a blah powder.
Uses
Tellurium is acclimated in alloys, mostly with chestnut and stainless steel, to advance their machinability. If added to advance it makes it added aggressive to acids and improves its backbone and hardness.
Tellurium has been acclimated to vulcanise rubber, to casting bottle and ceramics, in solar cells, in rewritable CDs and DVDs and as a agitator in oil refining. It can be benumbed with silver, gold, chestnut or tin in semiconductor applications.
Biological role
Tellurium has no accepted biological role. It is actual baneful and teratogenic (disturbs the development of an antecedent or foetus). Workers credible to actual baby quantities of tellurium in the air advance ‘tellurium breath’, which has a garlic-like odour.
Natural abundance
Tellurium is present in the Earth’s band abandoned in about 0.001 locations per million. Tellurium minerals cover calaverite, sylvanite and tellurite. It is aswell begin absolute in nature, but abandoned actual rarely. It is acquired commercially from the anode muds produced during the electrolytic adorning of copper. These accommodate up to about 8% tellurium.
