Tellurium dioxide comes in a white powder. Tellurium Dioxide is mainly used for the preparation of tellurium dioxide single crystal, infrared, acoustooptic, infrared windows materials, electronic components materials and antiseptics. Purity: 99%
Particle size range: 1-5 micron

Tellurium Oxide (TeO2) Powder:
Tellurium oxide and tellurium dioxide are both inorganic compounds. Tellurium oxide chemical equation is TeO2. White powder. White crystals. Tetragonal crystals, heating is yellow, melting dark yellow-red. They are slightly soluble and soluble both in water and in strong acids and alkalis. TeO2 tellurium dioxide is a solid oxide. It is found in two different forms, the yellow trapezoid b TeO2 tellurite mineral and the synthetic colorless (dicurellurite), a-TeO2. TeO2 can be a teratogen. Tellurium compounds produce ethyl tetrauridine, which gives off a strong garlic-like smell.

Performance and properties of Tellurium Oxide TeO2 Powder:
Tellurium oxide is an amphoteric compound that is not soluble in water, ammonia or strong acids, but it can be dissolved in alkalis and strong acids. This solid white tellurium oxide powder will turn yellowish when heated and dark yellowish brown after it has melted. Tellurium Dioxide is used in acoustooptic products and has good diffraction. It works at any power level.

How do you make Tellurium Oxide TeO2 Powder?
Tellurium oxide is precipitated out by nitric, or a mixture containing nitric and hydrochloric acids. After filtering, washing and drying, the impurities that have not been reacted are removed. This method requires a lengthy process, which produces a high amount of NO2 and N2O gas.
The reaction of tellurium and O2 produces a-TeO2.
TeO2 + TeO2
The alternative preparation is dehydrating the tellurium acid, H2TeO3, and thermally decomposing the basic tellurium Nitrate, Te2O4*HNO3, over 400 degC.

Tellurium Oxide TeO2 (powder)
Tellurium oxide can be used for a wide range of applications depending on its purity.
Rubber vulcanization accelerater, chemical additive for electroplating, tellurium dioxide single-crystal for optical devices.
Tellurium oxide is used in ceramics to color them.
Tellurium oxide is used more and more in optical refraction products, such as free products or fiber optics.
Tellurium oxide can be used for high-speed, high-resolution laser equipment.
Tellurium dioxide is used for the preparation of single crystal tellurium and infrared devices. It can also be used in electronic components, as well as preservatives. Polythene bottles are used for packaging.
Tellurium oxide also performs the following functions.
Use as an acoustooptic element.
Use for disinfection or identification of bacteria within vaccines.
The preparation of thermoelectric converter element, refrigeration element and piezoelectric cristal.
It is used in acoustooptic materials.
TeO2 glass is a glass with a high refractive indices and it can transmit to the mid infrared spectrum of electromagnetic radiation. This makes TeO2 glass a valuable material for optical waveguides. Tellurite glasses can have up to thirty times the Raman gains of silicon. They are useful in optical fiber amplifiers.
