Tellurium Dioxide Powder (Te02) General Description:
Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2. Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2

Density : 5.8g/cm3, Specific Gravity: 5.67, Melting Point: 733°C, Boiling Point: 1245°C, Water Solubility: insoluble, Appearance: white solid


Tellurium Dioxide Powder (Te02) Typical Applications:
It is used as an acousto-optic material.
Tellurium dioxide is also a conditional glass former, which means it will form a glass with small molar% additions of a second compound such as an oxide or halide. TeO2 glasses have high refractive indices and transmit into the mid-infrared part of the electromagnetic spectrum, therefore they are of technological interest for optical waveguides. Tellurite glasses have also been shown to exhibit Raman gain up to 30 times that of silica, useful in optical fibre amplification.
