Rare earth doped Refractory Metal/Oxide Matrix Functional Materials(2)

2014 International Conference on Functional Materials(ICFM 2014)——In this paper,two kinds of doped tungsten cathode were prepared by powder metallurgy method.The emission property and emission mechanism of the cathodes have been investigated.It shows that decreasing the grain size is favorable for the emission property enhancement and emission uniformity.
