Keywords:Ferroelectrics, Relaxor, Tungsten bronze

In the previous meeting, we presented that Ta/Zr subustituted KSr₂Nb₅O₁₅(KSN) tungsten bronze ceramics, KSr₂Nb_5-xTa_xO₁₅(KSNT) and K_1-xSr_2+xNb_5-xZr_xO₁₅(KSNZ), show the coexisting ferroelectric and relaxor properties. In this meeting, we will show the effect of Ta/Zr content on the T_C and T_m of KSNT/KSNZ.
