Аннотация
Nanopowders of neodymium ferrite with perovskite structure were synthesized by co-precipitation precipitation via hydrolysis of iron(III) and neodymium(III) cations in boiling water with addition of a 5% aqueous ammonia. NdFeO3 nanopowders formed after the annealing of precipitates at temperatures of 600 to 950°C for 1 h have particle sizes of 20 to 70 nm, respectively (TEM). Raising the annealing temperature from 600 to 950°C leads to an increase in the average crystal size from 18 to 27 nm (XRD). The samples synthesized in the study are magnetically hard materials.
