Flibe是一种由2LiF：BeF 2组成的熔盐，在磁聚变和惯性聚变中作为冷却介质和氚增殖介质具有重要意义。关键的安全问题是从意外引入的空气，潮湿的空气，或蒸汽到熔盐的蒸气和气溶胶的流动。动员试验进行了氩气，空气和潮湿的空气，使用一个经典的蒸发装置设计的蒸汽压测定。在500 ° C和800 °C之间在流动的氩气中测定的蒸气压，假设BeF 2和LiBeF 3为蒸气物种，比最近的蒸气压模型预测的低2-3倍。在所有环境中，动员率都相当。一些含锂物质随着温度的升高对总动员的贡献越来越大，在空气环境中的动员作用也越来越大。获得质量通量值（kg/m2 s）的估计值，并就熔盐增殖包层设计的安全评估的相关性进行评估。
Flibe a molten salt consisting of 2LiF:BeF2has interest as cooling and tritium breeding media in both magnetic and inertial fusion. Key safety issues are the mobilization of vapors and aerosols from accidental introduction of air, moist air, or steam to the molten salt. Mobilization tests were performed with argon, air and moist air using a classical transpiration apparatus designed for vapor pressure determinations. Vapor pressures determined between 500 and 800 °C in flowing argon, assuming BeF2and LiBeF3as the vapor species, are 2–3 times lower than those predicted by recent vapor pressure models. Mobilization rates were comparable in all environments. Some lithium-bearing species provides an increasing contribution to the overall mobilization with temperature and a greater role in mobilization in the air environments. Estimates of mass flux values (kg/m2s) are obtained and assessed with regard to relevance for safety assessments of molten salt breeder blanket designs.
