Anisotropic　Nd15.5Dy1.0FeBalCo3.0B6.8Al1.0　magnets　were　produced　by　the　spark　plasma　sintering　(SPS)　technique.　The　effects　of　processing　conditions　on　the　microstructure,　magnetic　properties,　dimensional　precision　and　density　of　the　magnets　were　studied.　The　magnetic　properties,　microstructure　and　constituents　were　investigated　by　means　of　a　magnetic　flux　density-magnetic　field　strength　(B-H)　loopline　instrument,　scanning　electron　microscopy　and　energy　dispersive　X-ray　analysis.　The　density　of　the　magnets　was　determined　by　the　Archimedes　method,　and　the　dimensional　precision　of　the　magnets　was　measured　by　micrometer.　It　was　found　that　the　microstructure　of　SPS　processed　Nd-Fe-B　magnets　is　unique,;　the　grain　size　is　fine　and　uniform　while　distribution　of　the　neodymium　rich　phase　is　heterogeneous.　The　optimal　magnetic　properties　of　SPS　processed　Nd-Fe-B　magnets　obtained　so　far　are　maximum　energy　product　of　240　kJ　m(-3)　and　coercive　force　of　1260　kA　m(-1).　The　dimensional　precision　of　the　magnets　is　similar　to20　mum,　and　the　density　of　the　magnets　reaches　7(.)58　g　cm(-3).
