“…where r t and r o are the cation radii of the tetrahedral sublattice and octahedral sublattice, respectively [47], and assuming that the radius of tetrahedrally coordinated O where <r t > and <r o > are the average cation radii for the tetrahedral sites and octahedral sites, respectively, λ, the inversion degree, is the fraction of tetrahedral sites occupied by Al 3+ according to the estimated site occupation factors, (r X n+ ,s ) are the effective cation radii, as expressed by Shannon [48], and x is the nickel-substituted cobalt fraction; adapted from [49,50]. The microstructure of the as obtained powders was studied after calcination by scanning electron microscopy (SEM) in a FEI Quanta 3D FEG apparatus (Thermo Fisher Scientific, Hillsboro, OR, USA) operating at accelerating voltages between 1 and 5 kV, using secondary electron images.…”
