Tellurium Dioxide Powder(TeO2) 5N 7446-7-３

About Tellurium Dioxide

The main resultant of tellurium burning in the air is tellurium dioxide. Tellurium dioxide can barely solve in water but can completely solve in concentrated sulfuric acid. Tellurium dioxide shows instability with powerful acid and powerful oxidant. As tellurium dioxide is amphoteric matter, it can react to acid or alkaline in the solution.

As tellurium dioxide has a very high possibility of causing deformity and is poisonous, when absorbed into the body, it can produce an odor (tellurium smell) similar to the smell of garlic in the breath. This kind of matter is the dimethyl tellurium generated by the metabolism of tellurium dioxide.

Wha is Tellurium Dioxide Powder used for?

Tellurium Dioxide (TeO₂) Powder is a high-performance inorganic compound renowned for its unique optoelectronic, thermal, and structural properties. Its versatility spans advanced technology sectors, scientific research, and industrial manufacturing, with critical applications including:

1. Acousto-Optic Materials 

   - Serves as the primary component in paratellurite single crystals (α-TeO₂), enabling ultrafast light modulation for:  

     ✓ Laser beam steering and frequency shifting  

     ✓ Optical communication systems (DWDM filters, Q-switches)  

     ✓ Ultrasonic imaging and real-time holography  

   - Exhibits exceptional acousto-optic figure of merit (M₂) for high-resolution devices operating in visible to mid-IR spectra.

2. Advanced Glass Systems  

   - Functions as a conditional glass former in specialty optical glasses:  

     ✓ Low-phonon-energy tellurite glasses for fiber amplifiers (Er³+/Pr³+-doped) in telecommunications  

     ✓ High-refractive-index glasses for infrared lenses and night vision optics  

     ✓ Radiation-sensitive glass for dosimetry and scintillation materials  

 3. Semiconductor Technology 

   - Critical precursor for II-VI compound semiconductors:  

     ✓ CdTe/CdZnTe crystal growth for X-ray/γ-ray detectors and solar cells  

     ✓ HgTe-based quantum dot synthesis for tunable IR photodetectors  

     ✓ Integration into topological insulator research (e.g., Bi₂Te₃/TeO₂ heterostructures)  

4. Energy Conversion Systems 

   - Enables high-efficiency thermoelectric devices:  

     ✓ Bismuth telluride (Bi₂Te₃) composites for Peltier coolers in microelectronics  

     ✓ Waste heat recovery modules (ZT >1.2 at 300-500K)  

     ✓ Cryogenic thermocouples for space exploration equipment  

5. Piezoelectric & Pyroelectric Devices 

   - Dopant in non-linear optical crystals (e.g., TeO₂-Li₂O systems):  

     ✓ Surface acoustic wave (SAW) sensors for gas detection  

     ✓ IR pyroelectric detectors with rapid response (<10ms)  

     ✓ Frequency-stabilized oscillators in 5G/6G base stations  

6. Emerging Applications 

   - Quantum material synthesis:  

     ✓ Template for 2D tellurene nanosheets in spintronic devices  

     ✓ Flux agent in high-Tc superconductor crystal growth  

   - Chemical vapor deposition (CVD):  

     ✓ Thin-film TeO₂ coatings for electrochromic smart windows  

     ✓ Resistive RAM (ReRAM) dielectric layers  

   - Nuclear technology:  

     ✓ Neutron shielding composites (TeO₂-PbO-B₂O₃ glasses)  

     ✓ Scintillator matrices for neutrino detection  

Key Advantages:  

- Broad optical transmission range (0.35–5 µm)  

- High chemical stability in acidic/oxidative environments  

- Tunable bandgap (3.7–4.2 eV) for tailored optoelectronics  

Note: Requires controlled handling due to moderate toxicity in powdered form. Applications often leverage its amphoteric nature and dual oxidation states (Te⁴+/Te⁶+).  

This multifunctional material continues to enable breakthroughs in photonics, sustainable energy, and quantum technologies, with ongoing research exploring its role in neuromorphic computing and terahertz waveguides.
