Tellurium dioxide is a inorganic compound, white powder. Mainly used for preparing tellurium dioxide single crystals, infrared devices, acousto-optic devices, infrared window materials, electronic component materials, and preservatives. The packaging is packaged in polyethylene bottles.
Application
Mainly used as an acoustooptic deflection element.
Used for preservation, identification of bacteria in vaccines, etc.
Preparation of II-VI compound semiconductors, thermal and electrical conversion components, refrigeration components, piezoelectric crystals, and infrared detectors.
Used as a preservative and also for bacterial testing in bacterial vaccines. It is also used for bacterial testing in vaccines to prepare tellurites. Emission spectrum analysis. Electronic component materials. preservative.
Preparation
1. It is formed by the combustion of tellurium in air or oxidation by hot nitric acid.
Te+O2→TeO2； Te+4HNO3→TeO2+2H2O+4NO2
2. Produced by thermal decomposition of telluric acid.
3. Tirafa.
4. The growth technology of tellurium dioxide single crystal: A type of tellurium dioxide (TeO2) single crystal growth technology that belongs to crystal growth technology. Its characteristic is that the crucible descent method can grow single crystals with various tangential directions and shapes. By utilizing this technology, rectangular, elliptical, rhombic, plate-like, and cylindrical crystals can be generated along the [100] [001] [110] direction and in any of these directions. The grown crystals can reach (70-80) mm × (20-30)mm × 100mm。 Compared with the general pulling method, this method has the advantages of simple equipment, no restrictions on pulling direction and cutting shape, basically no pollution, and can correspondingly increase the crystal utilization rate by 30-100%
