“…For these combinations of crystalline phases, not only a binary eutectic of K 2 CeCl 5 / 6 LiCl but also a ternary eutectic of CeCl 3 /SrCl 2 / 6 LiCl was identified as a new attempt based on the phase diagram database. [23,24]. In a previous study, a CeCl 3 / 6 LiCl binary eutectic scintillator was reported [21].…”

In recent years, thermal neutron detection using scintillators has been used in a wide range of fields. Thus, the development of scintillators with a higher light yield, faster decay, and higher sensitivity for thermal neutrons is required. In this study, K2CeCl5/6LiCl and CeCl3/SrCl2/6LiCl were developed as novel eutectic scintillators for thermal neutron detection. LiCl was selected as the neutron capture phase and K2CeCl5 and CeCl3 were used as the scintillator phases. The eutectics of K2CeCl5/6LiCl and CeCl3/SrCl2/6LiCl were prepared using the Vertical Bridgman method and the phases were identified by scanning electron microscopy and powder X-ray diffraction measurements. The results of radioluminescence measurements under Ag source X-ray tube irradiation confirmed that the 5d-4f emission derived from Ce3+. The cathodoluminescence spectra and thermal neutron responses of the prepared eutectics were measured to evaluate their optical properties.

“…The calculating flow of our computer program was based on the flowchart of the Calphad method in [13]. This computer program has been used to perform thermodynamic evaluation and optimization for some binary and ternary chloride molten salt systems [14][15][16]. In this program, the minimum Gibbs energy of the system was found through the algorithms of golden section search and parabolic interpolation, and the optimal model parameters were obtained by Nelder-Mead simplex algorithm [17].…”

In this study, the phase diagram of the NaCl+RbCl binary system was measured using differential scanning calorimetry, and the measured molar percentages of the binary mixture RbCl ranged from 12 to 97 mol%, updating and extending the experimental data for this binary system. The liquid phase of this system was thermodynamically modeled using a modified quasichemical model, and a computer optimization program for evaluation of the experimental data on phase equilibria and other thermodynamic data was developed based on this model. All thermodynamic models of the NaCl+RbCl binary system were constructed; calculations of the phase diagram, enthalpy of mixing, and activity coefficient of NaCl of the NaCl+RbCl binary system were completed using the obtained model parameters; and the calculated eutectic point positions were xRbCl = 0.567 and 550.2 °C. The calculated results were able to reproduce the various types of experimental data well, and the thermodynamic self-consistency between different types of experimental data was demonstrated.

“…In order to monitor the pryroprocessing process and optimize its design, thermodynamic assessment of actinides and lanthanides in LiCl-KCl molten salt is significantly needed. Even though several systems have been assessed, such as LiCl-KCl-CeCl3 [94,95] and LiCl-KCl-UCl3 [96], as one of the important lanthanide, GdCl3 in LiCl-KCl has not been evaluated.…”
