| 摘 要： | 铁电阴极材料，作为一种新型的功能材料，以其高的发射电流密度等优点而受到重视。鉴于目前研究的铁电阴极材料多局限于锆钛酸铅等含铅材料，作者采用无铅铁电陶瓷Na1/2Bi1/2TiO3-BaTiO3(BNBT)，进行了电子发射实验，获得发射电流密度达20A/cm2。初步实验结果表明，与锆钛酸铅相比，钛酸铋钠发射电流密度略低但性能稳定性较好。作为无铅铁电阴极，BNBT仍然具有良好的研究开发价值。

| Abstract: | Being a novel functional material, the ferroelectric cathode materials were studied well with the leaded materials for their high electron emission density. In this paper, the initial experiment of electron emission was carried out with the lead-free ferroelectric ceramics Na_(1/2) Bi_(1/2)Ti O_3 -BaTiO_3 (BNBT). High current density about 20A/cm~2 has been obtained with the excitation voltage around 11kV. In contrast with the lead zirconate titanate (PZT), BNBT's emission current density is lower but its parameter stability is better. The initial data show that BNBT is a potential lead-free ferroelectric cathode material. |
