Sodium technetate(V)

Sodium technetate(V) is an inorganic compound with the chemical formula NaTcO3. It is a perovskite material.

Preparation
Sodium technetate(V) can be prepared by co-heating technetium, sodium pertechnetate and sodium oxide, and decomposition occurs at high temperature. In addition, Na299MoO4 decomposed in a NaOH solution will also produce NaTcO3. The NaTcO3 puckering effect resembles NaMoO3 and the band between the egπ and a1g state disappears.

Properties
NaTcO3 is a black solid that is a member of the Na2O–Tc2O5 system. It is stable to 800 C.
