General Description
Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms the yellow orthorhombic mineral tellurite -TeO2 and the synthetic colourless tetragonal (paratellurite) -TeO2. Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite -TeO2.
