摘要: LiF–BeF2–ThF4 is a key system in molten salt reactor fuel studies. In this paper we give an overview of some important features ternary system. We discuss the phase behavior, vapor pressure, density and viscosity, based on what known literature our own data from previous work thermodynamic assessment LiF–BeF2–ThF4.
