tellurium dioxide applications

Tellurium Dioxide

Tellurium dioxide in its orthorhombic form occurs in nature as mineral tellurite. It is mined from natural deposits. Also, tellurium dioxide is produced as an intermediate during recovery of tellurium metal from anode slimes of electrolytic copper refining (See Tellurium, Production).

Tellurium Dioxide, TeO2

Tellurium dioxide possesses definite basic tendencies, the tellurium being capable of acting as a quadrivalent atom and the group TeO, telluryl, as a bivalent basic radical. When heated in a current of dry hydrogen chloride or with solid ammonium chloride, tellurium dioxide forms the tetrachloride.
