How is the tellurium oxide TeO2 powder produced?

How is Tellurium Oxide TeO2 powder produced?
With nitric acid or containing a mixture of nitric acid oxidation of elemental tellurium, get the original tellurium acid, then the original tellurium acid with a strong hydrochloric acid into tellurium tetrachloride, filter out the unreacted impurities reoccupy after alkali neutralization, precipitation out of tellurium dioxide, after filtering, washing, drying, will get rid of the low melting point impurity tellurium dioxide calcination, tellurium dioxide powder. The process flow of this method is long, and a large amount of NO and NO2 gas will be produced in the reaction process.
Paratellurite, α-TeO2, is produced by reacting tellurium with O2:
Te + O2 → TeO2
Alternative preparation is to dehydrate tellurous acid, H2TeO3, or to thermally decompose basic tellurium nitrate, Te2O4·HNO3, above 400 °C.

Overview of tellurium oxide TeO2 powder

Tellurium dioxide is an inorganic compound whose chemical formula is TeO2. White powder. White crystals. It has a tetragonal crystal structure, which is yellow when heated, and dark yellow-red when melted. It is slightly soluble in water, soluble in strong acids and alkalis, and forms double salts. Tellurium dioxide (TeO2) is a solid oxide of tellurium. It has two different forms: the yellow trapezoidal mineral β-TeO2 telluride and the synthetic colorless tetragon (cyanobacteria) α-TeO2.TeO2 may be a teratogen, and it will generate ethyl telluride when it comes in contact with tellurium compounds. Garlic flavor is produced on it.

Application of tellurium oxide TeO2 powder

Tellurium dioxide can be used in different fields depending on its purity and form.

Glass shaper for tellurite glass powder, single crystal tellurium dioxide for optical equipment, front silver paste for solar cells, rubber vulcanization accelerator, electroplating chemical additives.

Tellurium dioxide is sometimes used to color ceramics.

Tellurium dioxide has been increasingly used in optical refraction applications, such as optical fibers and free products.

Tellurium dioxide can even be used in high-speed or high-resolution equipment that needs to handle high laser power.

Tellurium dioxide is used to prepare single crystal tellurium dioxide, infrared equipment, acousto-optic equipment, infrared window materials, electronic components and preservatives. Packed in polyethylene bottles.

In addition, tellurium dioxide also has the following functions

Used as acousto-optic deflection element.

Used for disinfection, identification of bacteria in vaccines, etc.

Prepare two to six kinds of compound semiconductors, thermoelectric conversion elements, refrigeration elements, piezoelectric crystals and infrared detectors.

It is used as an acousto-optic material.

Tellurium dioxide is also an unwilling glass former, it will form glass with a small amount of mol% of the second compound (such as oxide or halide) under appropriate cooling conditions. TeO2 glass has a high refractive index and can be transmitted to the middle of the glass. The infrared part of the electromagnetic spectrum, so it has important technical value in optical waveguides. Tellurite glass also shows a silicon Raman gain of up to 30 times, which is very useful in fiber amplification.
