PuF₃ was synthetized by hydro-fluorination of PuO₂ and subsequent reduction of the product by hydrogenation. The obtained PuF₃ was analysed by X-Ray Diffraction (XRD) and found phase-pure. High purity was also confirmed by the melting point analysis using Differential Scanning Calorimetry (DSC). PuF₃ was then used for thermodynamic assessment of the PuF₃-LiF system. Phase equilibrium points and enthalpy of fusion of the eutectic composition were measured by DSC. XRD analyses of selected samples after DSC measurement confirm that after solidification from the liquid, the system returns to a mixture of LiF and PuF₃.

氢氟化法合成三氟化p和PuF ₃ -LiF体系的新热力学数据

PUF ₃由二氧化钚的水力氟化synthetized ₂和通过氢化随后还原产物。通过X射线衍射（XRD）分析所获得的PuF ₃并发现其为纯相。通过使用差示扫描量热法（DSC）的熔点分析也证实了高纯度。然后将PuF ₃用于PuF ₃ -LiF系统的热力学评估。通过DSC测量共晶组合物的相平衡点和熔化焓。DSC测量后，对选定样品的XRD分析证实，液体固化后，系统返回到LiF和PuF ₃的混合物。
