Procedure

Tellurate or tellurite glasses are prepared by starting with either telluric acid or tellurous acid, respectively. Weigh out 688.92 gm H2TeO4.2H2O or 532.83 gm of H2TeO3. Dissolve in 1000 ml. For H2TeO4, heating may be used to effect dissolution, but for H2TeO3, the solution must be kept cold, i.e. -- below 10° C. (About 50-75 ml of concentrated HCl may be added to aid dissolution of the H2TeO3). Weigh out 100.1 gm CaCO3 and dissolve into the acid solution to form a clear solution.
