摘要：
The equation of state (EOS) of Li3N has been determined by energy-dispersive x-ray diffraction (EDXD) using synchrotron radiation up to 35 GPa at ambient temperature. Both the hexagonal D-6h(4)(P6(3)/mmc) and the hexagonal D-6h(1)(P6/mmm) phases were present at ambient pressure. The D-6h(1)-structure completely transforms into the D-6h(4)-structure at modest pressure. The change in Gibb's free energy as a function of pressure for Li3N was calculated using the experimental EOS.
