【Abstract】 Much research has been done on one of the functional ceramics material K0. 5Bi0. 5Ti O3 based leadfree piezoelectric ceramics so far. The new progresses of these syntheses of the lead-free piezoelectric powders of KBT were reviewed. It discussed some synthetic method of KBT powders,sol-gel,hydrothermal,etc. The main problems and the advantages of various synthetic methods were also analysed and compared. Furthermore,the future development prospects of these syntheses are also presented.更多还原
