There are thus two main conclusions to the present study of NaA. The 29Si-NMR data demonstrate unequivocally that the ordering scheme for Si and Al is 4 0 and the neutron diffraction data show that the rhombohedral symmetry observed at room temperature and below can be attributed to ordering of Na(2) ions with R3c symmetry. The transition to cubic symmetry occurrs at about 335K. [Pg.156]
