What is Effect of particle size on the polycrystalline CeB6 cathode prepared by spark plasma sintering about?
The full densification polycrystalline cerium hexaboride (CeB 6 ) cathode material was prepared by using the spark plasma sintering (SPS) method in an oxygen free system. The starting precursor nanopowders with an average grain size of 50 nm were prepared by high-energy ball milling. The ball-milled nanopowder was fully densified at 1550 °C under 50 MPa, which was about 350 °C lower than the conventional hot-pressing method and it was also lower than that of coarse powder under the same sintering condition. The mechanical properties of nanopowder sintered samples were significantly better than that of coarse powder, e.g., the flexural strength and Vickers hardness were 211% and 51% higher than that of coarse powder, respectively. The electron backscattered diffraction (EBSD) result showed that the (100) fiber texture could be fabricated by the ball-milled nanopowder sintered at 1550 °C and the thermionic emission current density was measured to be 16.04 A/cm 2 at a cathode temperature of 1873 K.
