Abstract

The hydrogen pressure and reaction time were studied during the disproportionation of the ground SmCo4.8Zr0.2 alloy. The alloy ground at ν = 100 rpm for τ = 24 h disproportionates at 0.5 MPa hydrogen pressure within 15–30 min, the alloy ground at ν = 200 rpm for τ = 6 and 12 h disproportionates at 0.5 MPa hydrogen pressure, and the alloy ground at ν =  300 rpm for τ = 6 h disproportionates into SmHx and ht-Co below 0.1 MPa hydrogen pressure. Residues of the CaCu5–structure ferromagnetic phase were found among the disproportionation products.
