)- NbO3-xLiNbO3 (x=0.05, 0.06) is a promising high-temperature lead free piezoelectric ceramic. Key words: (K0.5Na0.5)NbO3-LiNbO3; lead-free piezoelectric ceramics; piezoelectric properties; perovskite 1...)NbO3-xLiNbO3, a complete solid solution with perovskite structure can be formed when x≤0.07[16]. Fig.1 shows the XRD profiles of the (1-x)(K0.5Na0.5)NbO3-xLiNbO3(x=0.06) powders calcined at 850 ℃ for 5 h......
at 600, 650 and 750℃. Key words: BET thin film; ferroelectric property; metal-organic decomposition; Bi-layered perovskite 1 Introduction Many researches have been done on candidates... It is obvious that the XRD peak corresponding to (117) reflection appears above 600 ℃. This indicates that the beginning of crystallization to a Bi-layered perovskite is below 600 ℃. From 600 ℃ to 750 ℃, BET......
