[Ca24Al24.08Zr3.92O64](4+)(4e(-))　electrides　are　ceramic　materials　with　low　work　functions　that　can　store　high-density　free　electrons.　So,　it　has　great　application　potential　in　electron　emission.　In　this　paper,　The　mixed　powders　of　CaO,　Al2O3,　ZrO2,　and　Al　in　a　certain　stoichiometric　ratio　were　used　as　precursors,　and　[Ca24Al24.08Zr3.92O64](4+)(4e(-))　blocks　were　fabricated　through　in-situ　reduction.　The　synthetic　block　samples　have　fewer　pores,　cracks,　and　impurities,　and　the　blocks＇　relative　density　reaches　99.6%.　At　the　same　time,　the　blocks＇　cages　were　injected　with　high-density　electrons　during　the　sintering,　and　the　electron　density　reached　2　x　10(21)　cm(-3).　This　makes　the　sample　realize　the　transition　from　insulation　to　conductor.　In　addition,　the　block＇s　emission　current　and　effective　work　function　is　1.75　A/cm(2)　and　2.25　eV,　respectively,　at　1100　&　DEG;C.　The　research　in　this　paper　provides　a　new　way　for　the　low-cost　and　industrial　production　of　high-quality　[Ca24Al24.08Zr3.92O64](4+)(4e(-)).
