Product Description
Shape: powder Material: Tellurium
physical size: powder
Dimensions: 99.999% Chemical Composition: TeO2
Product Feature
1,Chemical properties
TeO2 is highly insoluble in water and soluble in concentrated sulfuric acid. It is also incompatible with strong acids and strong oxidizing agents. It is an amphoteric substance and therefore can act both as an acid or as a base depending on the solution it is in. [4] It reacts with acids to make tellurium salts and bases to make tellurites. It can be oxidized to telluric acid or tellurates
Product Specification/Models
Tellurium dioxide: TeO2-05. Total content of Al, Ca, Cu, Fe, Mg, Ni, Pb & Se is below 10ppm
Application
It is used as an acousto-optic material.
Tellurium dioxide is also a conditional glass former, which means it will form a glass with small molar% additions of a second compound such as an oxide or halide. TeO2 glasses have high refractive indices and transmit into the MID-infrared part of the electromagnetic spectrum, therefore they are of technological interest for optical waveguides. Tellurite glasses have also been shown to exhibit Raman gain up to 30 times that of silica, useful in optical fibre amplification. [7]
