Product Description

High purity tellurium dioxide powder (α-TeO2)

This white solid TeO2 powder will become yellowish after heating and turn dark yellowish red after fusing.  As a kind of amphoteric compound, tellurium dioxide is basically insolvable in water or ammonia, yet solvable in strong acid and alkali.

The monocrystal of tellurium dioxide can be used in infrared and acousto-optic devices, especially as infrared windows, and used in electrical components, while tellurium dioxide TeO2 powder can be used as  rubber vulcanizing accelerator and catalyst or addictive in electroplating and conductive silver paste industries.

TeO2 powder can be used as rubber vulcanizing accelerator TDEC, brightener for electroplating and electroless plating, glass former and tellurium glass powder for solar cells' front-side silver photovoltaic paste.

Tellurium Dioxide can also be used as contitional glass former, which means it will form a glass with small molar additional of a second compound such as an oxide or holide.

TeO2 glasses have high refractive indices and transmite into the mid-infrared part of the eletromagnetic spectrum, therefore they are of technological interest for optical wavegnides.

Tellurite glasses have also been shown to exhibit Raman gain up to 30 times that of silica, useful in optical fiber amplication.
