(Na0.52?K0.44Li0.04)(Nb0.86Ta0.06Sb0.08)O3 (LTS-KNN) nano-powders with the size of 11-4?nm were prepared by a sol–gel method. Using the nano-powders, LTS-KNN ceramics with fine grain size of 200-00?nm and high density were fabricated by spark plasma sintering. The satisfied piezoelectricity is obtained, such as d * 33?~-81?pm/V, d 33?~-96 pC/N, K p?~-9.7?%, ε 33 T /ε 0?~-20, tanδ?~-.025 at 1?kHz and relative density is 99.4?%, respectively. It is shown that nano-powders are suitable to prepare fine-grained potassium-sodium niobate ceramics with satisfied properties.
