Abstract

Local structural changes that accompany amorphization during the decomposition of LiAl(ND₂)₄ were investigated by neutron total scattering measurements. Structure factors before the decomposition were attributed to single-phase LiAl(ND₂)₄ characterized by isolated [ND₂] units. Atomic pair distribution functions after heat treatments at 433 and 673 K showed that LiAl(ND₂)₄ decomposed to amorphous mixed phases that contain Li₃AlN₂ and AlN.
