Tellurium dioxide is a white powder. It’s used primarily to produce single crystals of tellurium dioxide, infrared and acoustooptic devices as well electronic components materials, antiseptics, and infrared windows materials.
Purity: 99%
Size range: 1-5 Micron
Tellurium Oxide TeO2 (powder)
tellurium dioxide (or tellingurium oxide) is an organic compound. It is also known as Tellurium dioxid Chemical Formula. The white powder. White crystals. The Tetragonal crystal structure is yellow when heated and then it melts to dark yellow-red. It can also be dissolved in water and dissolved in acid or alkali and forms double salt. Tellurium dioxide TeO2is a solid form of tellurium. You can find it in two forms, the yellow trapezoid mineral TeO2 tellurite or the synthetic colorless (dicurellurite), TeO2. TeO2 could be classified as a teratogen. Contact with tellurium compound may produce ethyltelluride.

Performance of Tellurium Oxide TeO2 powder:
Tellurium dioxide is an amphoteric chemical. Although it cannot be dissolved in water, ammonia or water, but can be dissolved in strong acids and alkali. Because of its unique qualities, tellurium dioxide is an integral component to acoustooptic products. It has good diffraction efficiency as well as being very efficient at all power levels.

How does Tellurium Oxide TeO2 be made?
Use nitric, or any mixture thereof, to get the original Tellurium Acid. Next, convert the original Tellurium Acid with strong Hydrochloric acid into Tellurium Tetrachloride. Finally, remove the remaining impurities after Alkali neutralization. This will allow you to precipitate out tellurium Oxid. It is a long process and will produce a significant amount of NO and N2 gas.
The reaction of tellurium and oxygen produces paratellurite.
Te + O2 → TeO2
Another alternative is to heat decompose tellurous acid at 400 °C, or dehydrate it with H2TeO3.
Applications of Tellurium OxideTE2 powder
You can use Tellurium dioxide in many different areas, depending on its purity.
For tellurite glass, tellurium dioxide single crystal for optical devices, for front silver paste, for solar cells, for rubber vulcanization accelerator and for electroplating chemicals additive.
Ceramics can sometimes be colored with tellurium dioxide.
The use of tellurium dioxide in optical refraction has increased, such as for fiber optics or free products.
Even high-speed, high-resolution equipment that uses high levels of laser power can be made with tellurium dioxide.
Single-crystal tellurium dioxide is prepared by using it in preparation of infrared and acoustooptic devices as well as electronic components and preservers. Polythene bottles are used for packaging.
Additionally, tellurium dioxide has the following functions.
It is used as an acoustooptic deflection component.
It is useful for identification and disinfection of bacteria, as well as in the preparation of vaccines.
Preparation of two to six compound semiconductors, thermoelectric convert element, refrigerator element and piezoelectric cristal.
It can be used to make acoustooptic materials.
Also, tellurium dioxide has the ability to form glass in a reluctant manner. Also, tellurite glasses have a Raman gain that is 30 times higher than silicon. This makes them useful in optical fiber amplifying.

Tellurium oxide TeO2 powder storage conditions:
Tellurium Oxide, TeO2 powder must be kept in a dry, cool environment.
