Tellurium Oxide, TeO2 powder:

Tellurium dioxide, Tellurium Oxide, is an organic compound. Tellurium oxide's chemical composition is TeO2. The white powder. White crystals. The Tetragonal crystal structure is yellow when it heats. It melts to dark yellow-red and forms double salt. Tellurium dioxide TeO2 is a solid form of tellurium. You can find it in two forms: the yellow trapezoid mineral TeO2 tellurite or the synthetic colorless (dicurellurite) TeO2. It is possible that TeO2 could be toxic. Contact with the tellurium compound may produce ethyl telluride. The resulting odor can be garlic-like.

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 alkalis. The solid white powder of tellurium dioxide will yellowish when heated and darken to yellowish brown after fusion. 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.

Technical Parameters of Tellurium O2 TeO2 powder:

How does Tellurium Oxide TeO2 (TeO2) powder get made?

Hydrogenation: Tellurium is placed in an atmosphere of hydrogen gas, heated to a suitable temperature to completely reduce it, and then heated to a higher temperature to separate the resulting tellurium oxide from the hydrogen gas. The reaction temperature is generally controlled at 300~500℃, and the reaction pressure is 1~5 bar.

Chlorine oxidation method: Tellurium is dissolved in a mixed solution of sodium chlorate and hydrochloric acid, and then hydrochloric acid is added to make the elements of chlorine and tellurium in the solution REDOX reaction to produce tellurium oxide.

Nitric acid oxidation method: Tellurium is placed in nitric acid solution, and by controlling the acidity and reaction temperature of the solution, tellurium oxide is oxidized to produce tellurium oxide. The reaction temperature is generally controlled at 50~100℃, and the reaction time is 1~3 hours.

High-temperature melting method: Tellurium is mixed with an appropriate amount of oxidizing agents (such as nitrate, chlorate, or permanganate) and heated to high temperatures to melt and oxidize it. The resulting tellurium oxide can be separated from the molten mixture and then washed and dried to produce the finished product.

Electrochemical method: Tellurium oxide is formed by the oxidation of tellurium ions through the action of electric current in the electrolyte. The optimum composition of the electrolyte and the optimum value of the current density need to be determined experimentally.
