摘要：

Sintering of a KSr2Nb5O15 powder compact at 1350°C resulted in a duplex structure. Prefiring of the compact between 1200° and 1300°C inhibited the abnormal grain growth responsible for the duplex structure. The Curie temperature and dielectric constant were dependent on the microstructure. Copyright © 1990, Wiley Blackwell. All rights reserved
