Abstract <p>Electron microscopy, X-ray fluorescence, gas, and X-ray diffraction analyses, and magnetometry are used to study the chemical and phase compositions and magnetic properties of a powder prepared by crushing and subsequent milling of end-of-life Nd–Fe–B sintered magnets, which is performed in an isopropyl alcohol medium. The milling processes used for the preparation of powder are among those comprising the manufacturing procedure of sintered NdFeB permanent magnets by powder metallurgy and should not change the phase composition of the alloy. The maximum powder particle size obtained after milling of the waste sintered permanent magnets is 50 μm. The prepared powder is found to be characterized by an increased oxygen content. The phase composition (wt %) comprises 82.0 % Nd₂Fe₁₄B, 9.7% Nd(OH)₃, 8.0% α-Fe, and 0.3% Nd₂O₃. The oxide phases are present at the powder particle surface. The powder material is shown to have the sufficiently high level of magnetic properties. The possibility of application of the powder in manufacturing sintered permanent magnets, in particular, by 3D printing technology is discussed.</p>
