Abstract：

The　carbonizing　process　of　Mo-La2O3　tubes　and　its　influence　on　the　tube＇s　emission　properties　were　analyzed.　It　was　indicated　that　carbonizing　causes　drastic　changes　in　the　morphological　structures　of　the　cathode,　and　the　diffusion　coefficients　of　La　in　Mo-C　were　five　orders　of　magnitude　in　the　case　of　La　in　Mo.　It　was　observed　that　the　carbonized　ratio　increased　with　the　increase　of　the　C6H6　pressure　when　the　pressure　was　low.　The　maximum　carbonized　ratio　reached　19.7　at　1.5×10　-2Pa　and　them　go　down　sharply　when　the　C6H6　pressure　was　over　1.5×10-2s　Pa.
