Abstract

The purpose of this work is the synthesis of Fe3BO6 nanoparticles for use as the main component in the chemical method for obtaining nanostructured Nd-Fe-B alloys. Amorphous Fe3BO6 nanoparticles prepared by chemical precipitation, FeCl3, and NaBH4 precipitant were used as precursors. Thermal treatment yielded Fe3BO6 crystalline nanoparticles. To determine the thermal effects and phase transitions were carried out: thermogravimetric analysis, differential scanning calorimetry (TG-DSC) and X-ray phase analysis (XRF). The morphology of the obtained nanoparticles was studied using scanning and transmission electron microscopy (SEM and TEM). It has been established that at a temperature of 530 °C, the complete formation of Fe3BO6∙3α-Fe2O3 occurs. The shape of the resulting Fe3BO6∙3α-Fe2O3 particles is incorrect, the average diameter of the nanoparticles was 50±10 nm.
