Tellurium Dioxide, has the symbol TeO 2 is a solid oxide of tellurium. Tellurium metal was first discovered by Franz-Joseph Muller von Reichenstein, but it was Martin Heinrich Klaproth who named the element in 1798 after the Latin word for "earth", Telus.3 in vacuum, disproportionating into tellurium dioxide, TeO 2 and elemental tellurium upon heating. Since then, however, existence in the solid phase is doubted and in dispute, although it is known as a vapor fragment; the black solid may be merely an equimolar mixture of elemental tellurium and tellurium dioxide.

1. Introduction . Tellurium oxide is one of the most attractive semiconductor materials, existing as both crystalline and amorphous phases. In particular, tellurium dioxide in crystalline form exists in two phase : paratellurite (tetragonal) and tellurite (orthorhombic). Tellurium dioxide has high acousto-optic figure ofThe contrast in structure and physical properties between silicon dioxide and carbon dioxide is interesting, as illustrated in . Solid carbon dioxide (dry ice) contains single CO 2 molecules with each of the two oxygen atoms attached to the carbon atom by double bonds. Very weak intermolecular forces hold the molecules together in the crystal.
