摘要

本文介绍了基于BaxSr1-xHfO3 (x = 0.25, 0.50, 0.75，质量W为16%，20%，24%，60%)的烧结压制复合材料的制备方法，以及这些材料热离子性能研究的实验结果。在T = 1620 K时，80% Ba0.75Sr0.25HfO3 - 20% W(质量)的热离子电流密度为1014 A/cm2。

1,000 A/cm2 cathode: To be or not to be?

Method of obtaining sintered and pressed composed materials based on Ba_xSr_1-xHfO₃, where x = 0.25, 0.50, 0.75, with 16, 20, 24, 60 % W (by mass), and experimental results of thermionic properties investigations of these materials are represented. The composition of 80% Ba_0.75Sr_0.25HfO₃ - 20 % W (by mass) is characterized by the thermionic current density of 1014 A/cm² at T = 1620 K.
