More info

Tellurium Dioxide Powder is a solid oxide of tellurium, which is a pure white color with the purity of 99.99%. 99.9% Tellurium Dioxide is a little yellowish powder compared with 99.99% Tellurium Dioxide due to the higher content of heavy metals content. High purity 99.99% Tellurium Dioxide with low heavy metal contents and nonexisting acid ions, so that it does not corrode metals and can increase product durability.

Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colorless tetragonal (paratellurite), α-TeO2. Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2.
