摘要： Disclosed herein is a permanent magnet comprising: a plurality of aligned iron nitride nanoparticles wherein the iron nitride nanoparticles include α″-Fe16N2 phase domains; wherein a ratio of integrated intensities of an α″-Fe16N2 (004) x-ray diffraction peak to an α″-α″-Fe16N2 (202) x-ray diffraction peak for the aligned iron nitride nanoparticles is greater than at least 7%, wherein the diffraction vector is parallel to alignment direction, and wherein the iron nitride nanoparticles exhibit a squareness measured parallel to the alignment direction that is greater than a squareness measured perpendicular to the alignment direction.

摘要： Disclosed herein is a rotary tube furnace configured to facilitate a chemical reaction between a solid mass and a gas in the furnace. The rotary tube furnace may comprise a reaction chamber extending through the furnace, the reaction chamber configured to control ingress and egress of each of the solid mass and the gas in the reaction chamber; a passage way configured to supply the solid mass to the reaction chamber; a passage way configured to supply the gas to the reaction chamber and circulate the gas through the reaction chamber; a heater providing heat to the reaction chamber and configured to control a reaction temperature in the reaction chamber; a magnetic field source in proximity to the reaction chamber for generating a magnetic field to one or more reaction zones of the reaction chamber; wherein the reaction chamber provides for mixing the solid mass and the gas.
