Abstract
The EMF method is applied to investigate the activity of sodium in a molten sodium–potassium alloy containing 87.2 wt. % of potassium. The measurements are performed in two different experimental setups. One of them uses glass containing sodium ions as electrolyte, and the other one uses beta-ceramics. Therefore, the limiting experimental temperature in the first case does not exceed 550 K, while in the second case, it is about 750 K. The maximal relative error of the experimental data on the activity of sodium in a liquid Na–K alloy is approximately 3%. The discrepancy between the measurement results and the experimental and theoretical data available in the literature is within this error.
