Sodium technetate(V) is an inorganic compound with the chemical formula NaTcO3.

It is a perovskite material and a rare example of an insoluble sodium salt.

[3] In addition, Na992MoO4 decomposed in a NaOH solution will also produce NaTcO3.

[4] The NaTcO3 puckering effect resembles NaMoO3 and the band between the eπg and a1g state disappears.

[5] NaTcO3 is a black solid that is a member of the Na2O–Tc2O5 system.
