Ammonium pertechnetate is a chemical compound with the formula NH₄TcO₄. It is the ammonium salt of pertechnetic acid. The most common form uses ⁹⁹Tc.^[1] The compound is readily soluble in aqueous solutions forming ammonium and pertechnetate ions.

Synthesis edit

It can be synthesized by the reaction of pertechnetic acid and ammonium nitrate:

HTcO₄ + NH₄NO₃ → NH₄TcO₄ + HNO₃

It thermally decomposes under inert atmosphere at 700 °C to technetium dioxide:

NH₄TcO₄ → TcO₂ + 2 H₂O + 1/2 N₂
