The NaNO3- KNO3 phase diagram

Many papers have been published in relation to the NaNO3-KNO3 phase diagram determination in the last 160 years. These papers fall in two categories: (1) the solid-liquid equilibrium is assumed to be of the eutectic type, and (2) the solid-liquid equilibrium is considered as a loop with a minimum. T...
