Liquidus surface in the HfO2-Y2O3-La2O3 system

Phase relations in the ZrO2–La2O3–Y2O3–Al2O3 system: Experimental studies and phase modelling

“…1 along with experimental phase diagram data. 18,[35][36][37][38][39][40][41][42] Calculated data for temperature and phase compositions of invariant reactions are presented in Table 2 along with available experimental data. [36][37][38]43 The thermodynamic data for the La 2 O 3 -Al 2 O 3 system were re-assessed taking into account standard entropy data, 29 heat capacity data 29,30 and solution calorimetric data [32][33][34] for LaAlO 3 , as well as phase equilibrium data.…”

Experimental investigation and thermodynamic modelling in the ZrO2–La2O3–Y2O3 system

“…1 together with available experimental data from works [20][21][22][23][24][25][26][27] and experimental data obtained in present study. The results of Mizuno et al [28] are not plotted in Fig.…”

Elemental surface enrichment in flame synthesis: A mechanism associated with particle melting-solidification

“…Referring to the simplified phase diagram in Fig. 7, at relatively low nominal Eu concentration, the Eu concentration in the liquid phase will always be higher than that in the solid phase, due to the positive slope of the Liquid/(Liquid + Hexagonal) phase boundary in the low Eu/Y region (right-hand-side) of the phase diagram [25]. In other words, Eu is concentrated in the remaining liquid phase as Y 2 O 3 :Eu solidifies.…”

“…There is no phase segregation in molten Eu 2 O 3 -Y 2 O 3 . In the solid phase, Eu 2 O 3 and Y 2 O 3 are isostructural; Eu 3+ ions can substitute Y 3+ ions in the Eu 2 O 3 -Y 2 O 3 system at any Eu/Y ratio and form solid solution [25].…”
