Sodium tellurite improves the corrosion resistance of electroplated nickel layers. Solutions of sodium tellurate are used for black or blue-black coatings on iron, steel, aluminum, and copper.
The main source of tellurium is from copper anode slimes, which contain precious metals as well as various tellurides. These slimes are roasted with sodium carbonate and oxygen to produce sodium tellurite.
Ag2Te + Na2CO3 + O2 = 2Ag + Na2TeO3 + CO2 (400-500°C)
