Phase Equilibria of the Binary System PuCl₃₋KCl

Thermodynamic evaluation of LiCl-KCl-PuCl3 system

“…The calculated phase is shown in Figure 3. Calculated melting point of K3PuCl6 is at 958 K, compared to the value of 958 K reported by Benz [15]. The peritectic point calculated for K2PuCl5 is at 35 at% KCl and 884 K, while the values of 35 at% KCl and 884 K reported by Benz [15] as well.…”

The peritectic point calculated for K2PuCl5 is at 35 at% KCl and 884 K, while the values of 35 at% KCl and 884 K reported by Benz [15] as well. Table 2 shows the optimized parameters for these binary systems and Table 4 is the comparison between the calculated results and the literature data.…”

“…The model separates anions and cations into different sublattices. There are two intermediate compounds in LiCl-KCl-PuCl3 system, K2PuCl5 and K3PuCl6 [15] and a previous study shows PuCl 6 3− prevails in Pu(III)-containing molten salt [16]. Accordingly, here K3PuCl6 is treated as a neutral species in anionic sublattice to deal with the short-range ordering.…”

“…The eutectic point occurs at 28% PuCl3 with a temperature of 734 K. The phase diagram of KCl-PuCl3 is a little more complex compared to the other two binary systems since two intermediate compounds were reported [15]: K3PuCl6 and K2PuCl5. K3PuCl6 melts congruently at 685 0 C and the peritectic point related to K2PuCl5 melting appears at 35% PuCl3 with a temperature of 611 0 C.…”
