Tellurium is a non-metallic element recovered as a by-product of electrolytic copper refining. Santech produces Tellurium in various shapes and sizes, such as ingot, powder and grains and a wide range of purity from 99.5% to 99.999%. Tellurium is a semiconductor that shows a greater electrical conductivity in certain directions which depends on atomic alignment, the conductivity increases slightly when exposed to light (photoconductivity). Tellurium is mainly used in the field of CdTe solar cell, Bi2Te3 thermo-electric compounds, metallurgy, vulcanization of rubber.
