Reversible thermal phase transition was observed for Y4Al2O9 at 1377°C with a hysteresis width of 78°C using differential scanning calorimetry. The enthalpy of the transition (ΔH) was about 300 cal/mol. Powder X-ray diffraction peaks of the high-temperature phase, as well as the peaks...
Sm3+ doped Y4Al2O9 (YAM) crystals were prepared by the micro-pulling down method. Optical-absorption and laser-selective-excitation techniques along with luminescence decays have been used to reveal that Sm3+ ions in YAM normally occupy four sites, which were characterized and discussed. The ...

In addition, strong anisotropic thermal expansion has been observed compared to Y4Al2O9 and Yb4Al2O9. The mechanism for low thermal conductivity is attributed to the lattice distortion and mass difference of the constituent atoms, and the anisotropic thermal expansion is due to the anisotropic ...
