| Abstract: | Some property control measures should be taken for producing fine-grained NKN,high density and excellent property piezoceramics,prepared by the traditional manufacturing process of ceramics.The measures mainly include the addition of sintering additives or introducing second component and doping and modification as well as MPB study and some adoption of n(Na)/n(K).Further more,the developing perspectives on(Na,K)NbO3-based lead-free piezoceramics are also put forward. |
