Description
Tellurium Dioxide is found in nature in two mineral forms tellurite (orthorombic) and paratellurite (α-TeO2). Due to its useful acousto-optic properties, is commercially produced on a large scale. . Each oxygen atom is bonded to two tellurium atoms with an angle of 140° between long and short bonds; other tellurium neighbors are at larger distances. Oxygen positions have no symmetry. Eight nonequivalent oxygen or interstitial sites and four nonequivalent tellurium sites can be distinguished. TeO2 is insoluble in water and has high refractive indices.


Applications
1. Front-side sliver paste
2. Chemical electroplating
3. 5N-single crystal
