Resumo
The NaF effect on microlite solubility at 800°C and 170, 200, and 230 MPa is studied experimentally. The immiscibility boundaries and compositions of fluid phases L1 and L2 are defined in the system NaF–H2O at 800°C. It is established that microlite solubility increase in the L1 phase, as compared with a homogeneous solution, is explained by the appearance in the L1 phase of “free” HF in an amount of 0.025 ± 0.003 mol kg–1 H2O. The model of “acidification” L1 and “alkalizing” L2 is supposed.
