摘要：

In　this　paper,　the　polycrystalline　CexPr1-xB　6　(0x0.6))　bulks　were　successfully　fabricated　by　spark　plasma　sintering　(SPS).　A　lot　of　experiments　are　conducted　to　testing　the　mechanical　and　emission　properties.　The　technological　applications　parameters　are　following:　the　sintering　temperature　is　1450°C,　the　sintering　pressure　is　50　MPa　and　the　holding　time　is　5　min.　The　maximum　pulse　thermionic　emission　density　of　Ce0.6Pr0.4B6　is　47.3　A·cm2　at　1973K　with　voltage　up　to　950　V.　©　2012　IEEE.
