Abstract

The concentration and temperature dependences of pyrochlore and Nb oxide solubility in Na2CO3 and Na2СO3 + NaF aqueous solutions with concentrations from 0.01 to 2.0 m at 300–550°C and 50 and 100 MPa (the Co–CoO buffer) are studied. It is established that the Nb equilibrium content in the solution increases at 550°C and 100 MPa with an increase in mNa2CO3 and reaches the value of 10–4 m. The Nb2O5 solubility almost does not change as the concentration of Na2CO3 increases and is found within 10–6 to 10–5.5 m.
