摘要：

The expansion of TiB2/C compound cathode during electrolysis was studied in laboratory. It was found that the expansion of TiB2/C compound cathode decreases with the increase of TiB2 content in TiB2/C. Na had the same penetration mechanism in TiB2/C cathode as that in normal carbon cathode. In TiB2/C cathode, Na not only penetrated into TiB2/C through pores, but also penetrated into TiB2/C through carbon grains inside TiB2/C cathode. Meanwhile, Na acted with carbon inside TiB2/C to produce compound among grains and hence led to grain expansion. It showed that there was linear relation between the depth of Na penetration of the TiB2/C cathode and t(1/2).
