摘要：
Using the Archimedean method the densities of melts in the KF-KCl-KBF4 system were determined. The temperature dependences of the density of individual mixtures were described by linear functions q = a - bT. On the basis of the measured densities the molar volumes and the excess molar volumes at the temperatures of 1000, 1100, and 1200 K were calculated. The dependence of the molar volume on composition was described using the regression equation (Graphics) It was found that the molar volumes of the investigated melts are close to the additive values.
