Glass samples containing 3 wt % of KTcO4 have been synthesized in the system, mol %: 40Na2O–10Al2O3–10Fe2O–40P2O5. The glass samples have been studied by X-ray photoelectron spectroscopy. It was found that the degree of technetium oxidation is Tc(IV), which differs from the behavior of rhenium under similar conditions: about 83% of Fe is present as Fe(III), and the rest, as Fe(II). A high stability of the lass against leaching at 90°C was demonstrated in the half-dynamic test (State Standard R 52126–2003): the rate of Tc leaching from the glass is about 3 × 10–6 g/(cm2 day).
