Tellurium Dioxide Powder | TeO2 | CAS 7446-07-3

Tellurium Dioxide (TeO2) Powder is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO₂, and the synthetic, colorless tetragonal (paratellurite), α-TeO₂. High-purity 99.99% Tellurium Dioxide Powder is white, while the 99.9% purity version has a slight yellowish color due to higher heavy metal content. The 99.99% pure powder has lower heavy metal content and no acid ions, making it non-corrosive to metals and improving product durability.

Products:

Application:

• Used as the acoustic-optical deflection element.
• Used for anticorrosion, identification of bacteria in vaccines, etc.
• Used in preparing the II-VI family compound semiconductor, thermal, electric conversion elements, cooling elements, piezoelectric crystals, and infrared detectors.
• Used in emission spectral analysis. 

Advantage:

• Nonexisting acid ions, that will not corrode metals and can increase product durability. Each content of Cu, Fe, Pb, Cd, Ni, As, is less than 5ppm by wt to the 99.999% grade.
• Strict quality control for procedures of raw material, process control, and pre-delivery.

Packing:

Tellurium Dioxide (TeO2) Powder is carefully packaged in carton boxes with foam protection to minimize damage during storage and transportation and to preserve the quality of our products in their original condition. The vacuum packing is 1kg/bag, 25kg/barrel, or based on specific requirements.
