Tuning the melting point and phase stability of rare-earth oxides to facilitate their crystal growth from the melt
文献摘要：
The challenge of growing rare-earth(RE)sesquioxide crystals can be overcome by tailoring their structural stability and melting point via composition engineering.This work contributes to the advancement of the field of crystal growth of high-entropy oxides.A compound with only small REs(Lu,Y,Ho,Yb,Er)2O3 maintains a cubic C-type structure upon cooling from the melt,as observed via in-situ high-temperature neutron diffraction on aerodynamically levitated samples.On the other hand,a compound with a mixture of small and large REs(Lu,YY,Ho,Nd,La)2O3 crystallizes as a mixture of a primary C-type phase with an unstable secondary phase.Crystals of compositions(Lu,YY,Ho,Nd,La)2O3 and(Lu,Y,Gd,Nd,La)2O3 were grown by the micro-pulling-down(mPD)method with a single monoclinic B-type phase,while a powder of(Lu,Y,Ho,Yb,Er)2O3 did not melt at the maximum operating temperature of an iridium-rhenium crucible.The minimization of the melting point of the two grown crystals is attributed to the mismatch in cation sizes.The electron probe microanalysis reveals that the general element segregation behavior in the crystals depends on the composition.
