Abstract
- We reported the new synthesis of Sm<subscript>2</subscript>Co<subscript>17</subscript> particles by a microwave-assisted combustion (MACS) method. This process enables the controlled decomposition of Sm(NO<subscript>3</subscript>)<subscript>3</subscript> and Co(NO<subscript>3</subscript>)<subscript>2</subscript> into SmCo-O particles, followed by calcium reduction-diffusion. This SmCo-O particle provides an approach for achieving high magnetic properties in Sm<subscript>2</subscript>Co<subscript>17</subscript> magnetic materials. The rhombohedral Sm<subscript>2</subscript>Co<subscript>17</subscript> particles can be incorporated into epoxy resin and oriented, displaying a square-like hysteresis loop. The particles display magnetic properties at room temperature, with a saturation magnetization of 112.3 emu/g, coercivity of 5.6 kOe, and a maximum energy product of 9.4 MGOe. This method improves the synthesis efficiency of rare earth cobalt-based nano-materials, expands the synthesis scope, and provides ideas for the synthesis and applications of other rare earth nano-materials.
