英文摘要：

　With the need of sustainable development and the legislation on lead-free being enforced in some developed countries,especially for the non-lead contained in electronic components,alkali niobate lead-free piezoelectric ceramics have been attracted more attention with their superior properties and higher Curie temperature.According to the reports of KNbO3-NaNbO3（KNN）-based lead-free piezoelectric ceramics in recent years,the current progresses of the preparation technique,such as powder preparation,molding,sintering,templated grain growth（TGG）,and reactive templated grain growth（RTGG）, of KNbO3-NaNbO3 based ceramics have been reviewed.The future preparation technique of KNbO3-NaNbO3 based piezoceramics has been described.
