| Abstract: | In this research we adopted a sol-gel method,with niobium oxalate as niobate resource,glycol as esterifying agent to obtain SrTiO3-KNN lead-free piezoelectric ceramics powder.TG/DSC was adopted to study the compositions of the xerogel and all the synthesis process,in order to find out the mechanizations of the sol-gel process.The crystal structure and surface feature was characterized and observed by XRD and SEM,the SrTiO3 best doping ratio and effect of sintering temperature on electrical properties were studied. |
