In　present　study,　sintered　Nd-Fe-B　permanent　magnets　with　different　compositions　were　fabricated　by　using　both　Spark　Plasma　Sintering　(SPS)　technique　and　conventional　sintering　technique.　Microstructure　and　compositions　of　both　magnets　are　observed　by　scanning　electron　microscope　with　energy　dispersive　X-ray　detector.　Magnetic　properties,　mechanical　properties,　and　chemical　stabilities　of　both　Nd-Fe-B　magnets　are　investigated.　Compared　with　the　conventional　sintered　magnets,　SPS　Nd-Fe-B　magnets　possess　comparable　magnetic　properties,　better　corrosion　resistance　and　mechanical　properties.　Further　investigation　shows　that　the　good　all-around　properties　of　the　SPS　magnets　result　from　their　unique　microstructure.　In　detail,　the　grain　size　of　Nd2Fe14B　main　phase　is　fine　and　uniform,　only　a　few　Nd-rich　phase　forms　along　the　grain　boundaries　of　Nd2Fe14B,　while　most　of　them　agglomerates　into　the　triple　junctions.　As　a　result,　SPS　process　is　expected　to　be　a　promising　method　for　the　production　of　new　Nd-Fe-B　magnets　with　good　all-around　properties.
