| Popis: | Lead-free piezoelectric ceramics with 0.96(K0.48Na0.52)0.95Li0.05Nb1−xSbxO3–0.04BaZrO3 (0.07 ≤ x ≤ 0.09) and 1 mol% CuO (KNLNSx–BZ–CuO) compositions were prepared with hard characteristics for possible application on piezoelectric transformers. The results showed that good piezoelectric properties were found for ceramics with x = 0.07 and 0.08 (d 33, d 31 and k p were similar for both compositions). The higher mechanical quality factor (Q m) corresponds to x = 0.07, which was close to 770. This combination of properties make the KNLNSx–BZ–CuO compositions promising materials for high power applications. |
