Abstract: Tellurium of high purity (99.999%) was prepared from technical tellurium (99%) through oxidation to tellurium dioxide, dissolution in NaOH, changing into Na2TeO4 by treatment with Na2S·9H2O and H2O2, successively. The HCl solution of Na2TeO4 was then treated with SO2 gas to give high purity tellurium.

Key words: high purity tellurium, preparation, purification
