中文摘要：

研究了在铌酸钾钠基陶瓷中,A位等价与非等价取代对陶瓷极化温度和极化电场的影响,结果表明：A位等价取代的陶瓷对极化温度和极化电场没有强烈依赖性,可以使极化足够充分,能有效提高铌酸钾钠基陶瓷的压电性能;相反,A位非等价取代的陶瓷对极化温度和极化电场敏感,容易击穿,极化不充分,限制了铌酸钾钠基陶瓷的压电性能.

英文摘要：

The effects of A-site equivalence and non-equivalence substitution on polarization temperature and electric field of K0.5Na0.5NbO3 lead-free piezoelectric ceramics are studied,and the results show that the ceramics sample of A-site equivalence is independent of polarization temperature and electric field,which can improve the piezoelectric constant.On the contrary,the ceramics sample of A-site non-equivalence substitution is sensitive to polarization temperature and electric field,constraining the piezoelectric properties.
