High Purity Tellurium Oxide TeO2 powder CAS 7446-7-3, 99.9% | Lemondedudroit

Tellurium dioxide is a white powder. It’s used primarily to produce single crystals of tellurium dioxide, acoustooptic devices, and infrared windows materials.
Purity: 99%

Particle sizes: From 1 to 5 micron

Tellurium Oxide, TeO2 powder:

Tellurium dioxide, telluriumoxid are both inorganic compounds. Tellurium oxide chemical composition, is TeO2. 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 soluble and dissolved in alkali and strong acids 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 dangerous. It can also react with tellurium compound, producing ethyltelluride. The teratogen is a potential cause of a bad breath.

Tellurium Oxide powder TeO2 performance:

Tellurium dioxide can be dissolved in water, ammonia or other amphoteric compounds, but it is soluble in strong acids and alkali. The solid white powder of tellurium dioxide will yellowish when heated and darken to yellowish brown after fusing. Because of its unique qualities, tellurium dioxide can be used in acoustooptic products. It has good diffraction efficiency as well as being very reliable at all power levels.

How does Tellurium Oxide TeO2 (TeO2) powder get 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 of Tellurium Dioxide. It is a long process and will produce a significant amount of NO2 and NO3 gas.

By reacting tellurium to O2, paratellurite is made.

Te + O2

An alternative preparation would be to heat decompose tellurous acid, H2TeO3, at 400°C, or to dehydrate tellurous acids, H2TeO3, above 400°C.

Tellurium OxideTE2 powder

Tellurium dioxide can be used for a variety of purposes depending on how pure it is.

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-powered equipment that uses high levels of laser power can be fitted 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 Powder:

Tellurium Oxide, TeO2 powder must be kept in a dry, cool environment.
