本文系统地研究了用于高性能低烧多层陶瓷的铅基弛豫铁电陶瓷的组成、显微结构和介电性能。所制备的Y5V、Y5U和X7R多层电容器不仅具有高的介电常数、低的烧结温度，而且具有低的老化速率、良好的偏置场特性和击穿强度以及与普通中高温多层电容器相当的优异的可靠性。基于PMN的低烧MLC已经商业化，显示出广阔的应用前景。
The composition, microstructure and dielectric properties of lead-based relaxor ferroelectric ceramics used for high performance low firing MLCs have been studied systematically. The Y5V, Y5U and X7R MLCs fabricated not only exhibit high dielectric constant, low sintering temperature but also have low ageing rate and good biased field behaviour and breakdown strength and excellent reliability comparable to that of normal middle and high sintering temperature MLCs. Low-firing PMN-based MLC has been commercialized and shows a wide application prospect.
