Phase equilibria and thermodynamic analysis of liquid–liquid immiscibility in the system SiO2–Na2O–MoO3 Open
Phase equilibrium experiments were carried out in the SiO 2 –Na 2 O–MoO 3 system at 1200ºC and 1000ºC. We found that immiscible phase region in this system is narrower than that reported previously. By combining phase relationship and ther…

Crystallization of molybdenum oxide phase from simulated high-level waste glass under slow cooling Open
In the vitrification of high-level radioactive waste, it is important to understand the crystallization behavior because precipitation of molybdenum (Mo) phase reduces the chemical durability of the waste form. In this study, the crystalli…

Estimation of Redox Condition of Simulated High-level Waste Glass Based on the Chemical Composition of Crystalline Phases of Platinum-group Elements Open
The redox condition of simulated high-level waste (HLW) glass was investigated by thermodynamic calculations for the phase equilibrium of crystalline phases composed of platinum group elements (PGE, Pd, Rh, and Ru) based on the thermodynam…
