| Abstract Scope |
There is a growing need to measure the thermophysical behaviors of molten salts at high temperatures as a variety of processes rely on these properties. Molten salts are used in a variety of high-temperature industrial applications, such as metal electrolysis, nuclear reactors, energy storage, etc. The measurement of their thermal properties, however, has long been a difficult task due to measurement difficulties at high temperatures and reactivity with the container materials. In this work, a novel, highly-integrated, table-top instrumentation is developed to measure the viscosity, surface tension, density, and vapor pressure of molten fluorides utilizing a micro-heater device. Incorporating falling sphere viscometry and maximum bubble pressure method, rapid, accurate measurements are made with only a few grams of a given sample. Measured values are compared with simulated results yielding low margins of error, demonstrating the validity of this novel instrumentation for investigation of unknown molten salt systems. |
