Validation of a New Design of Tellurium Dioxide-Irradiated Target
There are two methods of I-131 production in nuclear research reactors. One involves the irradiation of tellurium targets and the other uses uranium targets. Production of iodine-131 from tellurium dioxide, TeO 2, requires a target that meets the safety requirements (homogeneity of welds, leak tightness, resistance to irradiation conditions, …

Production of high purity TeO2 single crystals for the study of
Tellurium dioxide is found in nature in two mineral forms tellurite (orthorombic) and paratellurite (α-TeO 2). The latter has a tetragonal symmetry D 4(422) and due to its useful acousto-optic properties, is commercially produced on a large scale. First crystal synthesis using Czochralski method was reported in 1968 [4]. The first Bridgman ...

Tellurium Price And Trading Guide
In nature, tellurium is contained in trace amounts inside the copper ore. Commercial-grade tellurium has a purity of 99.5% but higher grades of purity are also available. Producing a more refined grade of tellurium calls for yet another process. First, tellurium dioxide has to be dissolved in hydrochloric acid.

How do I separate tellurium dioxide from silicon dioxide?
How do I separate tellurium dioxide from silicon dioxide? TeO2 is soluble in strong acids and alkaline metal bases. SiO2 is not soluble in acids except hydrofluoric acid and weakly soluble in hydroxides. Therefore, you can stir a mixture of TeO2 and SiO2 in a solution of concentrated HCl or H2SO4 and the TeO2 will dissolve, probably by …
