A　new　kind　of　cathode,　LaC2-Mo　cathode　was　prepared　through　spark　plasma　sintering　method　by　using　the　mixed　powder　of　LaC2　which　was　prepared　by　vacuum　melting　method　and　molybdenum.　It　was　found　that　the　emission　properties　of　LaC2-Mo　cathode　increases　with　the　LaC2　content　increasing.　The　emission　current　density　of　LaC2-Mo　cathode　which　contains　3.5wt.%　LaC2　could　reach　0.90A/cm(2)　at　1400　b　whereas　that　of　LaC2-Mo　cathode　with　10wt.%　LaC2　could　reach　3.02A/cm(2)　at　1400　center　dot　b.　Richardson　Work　function　of　LaC2-Mo　with　LaC2　3.5wt%　is　2.53eV.
