Density values of molten LiCl–ZrF4 and LiCl–KF–ZrF4 mixtures were obtained for the first time using the method of maximum pressure in the gas vial. The research was performed in three-component salt systems at molar ratio of alkali metal halides equal to 1 : 3, 1 : 1, 3 : 1. Temperature dependences of density were found for all structures of melts . Molar volumes and their relative deviations from ideality of salt mixes of LiCl–ZrF4 and LiCl–KF–ZrF4 systems were calculated. Conclusions concerning structure of the studied melts from the position of modern views on a structure of ionic liquids were made.
