Tellurium dioxide is used to fabricate fiber optics and pigments and to color ceramics and glass.
Aurubis is one of the world’s largest producers of high-quality tellurium. It is recovered from a variety of primary and secondary raw materials. Through the production processes in our copper smelters, we ensure a continuous supply of tellurium metal and tellurium dioxide.
Furthermore, both tellurium metal and tellurium dioxide from Aurubis fulfill the REACH requirements.
