A device for measuring the density and surface tension of melts

摘要

A method was developed and an experimental device was constructed for measuring the density and surface tension of melts. The hydrostatic method was used with the application of a volute-spring balance, which significantly simplified the device design. Its operation was tested by measuring the density and surface tension of a LiF melt in a temperature range of 1160-1350 K. The measurement errors are 1.5-2% and 10%, respectively.
