Tellerium Lump 99.999+% (Metal Basis)
Tellurium is a chemical element with symbol Teand atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur. It is occasionally found in native form as elemental crystals.
Tellurium is used in cadmium telluride (CdTe) solar panels. National Renewable Energy Laboratory lab tests of tellurium demonstrated some of the greatest efficiencies for solar cell electric power generators. Massive commercial production of CdTe solar panels by First Solar in recent years has significantly increased tellurium demand.[45][46][47] Replacing some of the cadmium in CdTe by zinc, producing (Cd,Zn)Te, produces a solid-state X-ray detector, providing an alternative to single-use film badges.
