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. [2]
Sodium technetate(V) can be prepared by co-heating technetium, sodium pertechnetate and sodium oxide, and decomposition occurs at high temperature. [3] In addition, Na99
2MoO4 decomposed in a NaOH solution will also produce NaTcO3. [4] The NaTcO3 puckering effect resembles NaMoO3 and the band between the eπ
g and a1g state disappears. [5]
NaTcO3 is a black solid that is a member of the Na2O–Tc2O5 system. It is stable to 800 °C (1,470 °F; 1,070 K). [1]
