<001> -textured 0.99(K0.49Na0.49Li0.02)(Nb0.97-xSb0.03Tax)O-3-0.01CaZrO(3) [abbreviated as 0.99KNLN(0.97-x)ST(x)-0.01CZ, x = 0.03, 0.07, 0.10, 0.15, 0.20, 0.25] ceramics were prepared by templated grain growth (TGG) method and a two-step sintering process. Giant longitudinal piezoelectric coefficient d(33) (391 pC/N) and piezoelectric strain coefficient d(33)* (630 pm/V under an AC E-field of 20 kV/cm) can be obtained in the textured ceramics with x = 0.25. All textured ceramics display superior k(p) (>54%) and g(33) (>23 x 10(-3) Vm/N) which are in an order of magnitude with PZT ceramics. The maximum value of k(p) (similar to 63.3%) obtained in textured ceramics with x = 0.15 is higher than that of famous textured LF4 ceramics. Excellent comprehensive properties suggest that <001> -textured 0.99KNLN(0.97-x)ST(x)-0.01CZ ceramics are promising candidates in the field of lead-free piezoelectric materials.
