Keywords:Ferroelectrics, Relaxor, Tungsten bronze

In the previous meeting, we presented that Ta/Zr subustituted KSr2Nb5O15(KSN) tungsten bronze ceramics, KSr2Nb5-xTaxO15(KSNT) and K1-xSr2+xNb5-xZrxO15(KSNZ), show the coexisting ferroelectric and relaxor properties. In this meeting, we will show the effect of Ta/Zr content on the TC and Tm of KSNT/KSNZ.
