Useful:

• Uses: Telluric acid dihydrate is used in the preparation of tellurium nanorods through hydrazine-driven reduction, which finds application in solar cells, thermoelectric and topological insulators. It is also involved in the preparation of tellurium metal by reacting with the solution of potassium thiocyanate.

Technology Process of TELLURIC ACID

There total 4 articles about TELLURIC ACID which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

tellurium(IV) oxide (7446-07-3) + water (7732-18-5) → telluric acid dihydrate (13451-14-4)

Guidance literature:

With dihydrogen peroxide; In water; oxidation of freshly pptd. Teo2 in aq. suspension with H2O2(30% aq.);;

Reference yield:

orthotelluric acid (7803-68-1) → metatelluric acid (13451-14-4)

Guidance literature:

With alkali hydroxide; In water; in the presence of alkali hydroxide, equilibrium;;

Reference yield:

orthotelluric acid (7803-68-1) → H2TeO4*1.32H2O (13451-14-4)

Guidance literature:

In neat (no solvent); pure H6TeO6 was heated in a closed tube at 150 °C for 2h, the formed colorless liquid was cooled and solidified at -10 °C, weight constance was obtained by storing in an open ampulla in vacuum for 3 months;;
