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.
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
