those that cannot be effectively or economically collected and processed). Using water, tellurites are then leached from the remaining material and converted to tellurium dioxide (TeO2). Tellurium has no known biological role. The higher the value, the larger risk there is to supply. Tellurium is one of the most rare, stable and solid elements in the earthâs crust. Check for the weaker Te3p peaks, if tellurium concentration is high enough. Tellurium's ability to form compounds with gold - a property that is unique to the metalloid - led to its role in Western Australia's 19th-century gold rush. CAS number
Tellurium is a semiconductor that shows a greater electrical conductivity in certain directions depending on atomic alignment; the conductivity increases slightly when exposed to light (photoconductivity). A higher recycling rate may reduce risk to supply. Boiling point
