This work presents an experimental study on LiAlO2 at pressure up to 5.0 GPa at 389 K by using large-volume static high-pressure technology. X-ray diffraction analysis shows that a pressure-induced grain size reduction in LiAlO2 has been observed. The grain size reduces from ~70 nm to ~ 20 nm after high-pressure treatment. It has the implications to the high-pressure behavious of LiAlO2 and the synthesis of nano-scale materials under high pressure.
Keywords:High Pressure; LiAlO2; Grain Size;
