Tellurium
Pellets
Ingots
Tellurium (Te) belongs to the family of metalloids. It is a substance of silvery-white color with metallic luster, brittle. It was first found in gold-bearing ores in Transylvania in 1782 by mining inspector Franz Josef Muller (Baron von Reichenstein). Its main source is sludge from the electrolytic refining of copper and lead.
TELLURIUM is used for thermoelectric alloys and in compounds for the production of semiconductors, optical devices, solar cells, etc.
