| Abstract: | We have synthesized a single crystal of lithium amide (LiNH2, LiND2) by melting method, and performed neutron diffraction of the single crystal at variable temperature. LiND2 is tetragonal structure and I-4 space group. Lattice parameters and unit cell volume of LiND2 at room temperature, 50℃, 100℃, 150℃ and 200℃ were determined. Both of the lattice parameters and the unit cell volume increase with increase of temperature. From these results, we have estimated coefficient of volumetric thermal expansion αv of LiND2 to be 222 * 10^[-6]/K. With increase of temperature, all thermal ellipsoids gradually expand because of thermal vibration. |
