Experimental data were obtained on the kinematic viscosity of 0.75LiF–0.2BeF₂–0.05ThF₄ melt in the temperature range 920–1155 K in order to substantiate the concept of a reactor with circulating fuel based on molten salts of lithium, beryllium, and thorium metal fluorides with added fissile materials. It is shown that the obtained viscosity is described by an exponential dependence on the reciprocal of the absolute temperature. The parameters of this dependence were determined. It is shown that the viscosity of the composition under study is described by the equation for a normal liquid at temperatures above 920 K.

0.75LiF– 0.2BeF2–0.05ThF4 熔盐运动粘度的测量

获得了 0.75LiF–0.2BeF ₂ –0.05ThF ₄熔体在 920–1155 K 温度范围内的运动粘度的实验数据，以证实具有基于锂、铍和铍熔盐的循环燃料的反应堆的概念。添加了裂变材料的钍金属氟化物。结果表明，获得的粘度由对绝对温度倒数的指数依赖性描述。确定了这种依赖性的参数。结果表明，所研究的组合物的粘度由温度高于 920 K 时正常液体的方程描述。
