A位等价与非等价取代对（K0.5Na0.5）NbO3陶瓷极化的影响
Effects of A-site equivalence and non-equivalence substitution on polarization properties of （K0.5Na0.5）NbO3 lead-free piezoelectric ceramics
摘要
Abstract
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.关键词
