Effect of various sintering aids on the piezoelectric and dielectric properties of 0.98(Na0.5K0.5)NbO3–0.02Li0.04(Sb0.06Ta0.1)O3 ceramics
چکیده انگلیسی


• Effect of various dopants on electrical and dielectrical properties was investigated.
• Each samples with various dopants show different performance.
• The 0.98NKN–0.02LST doped CuO can be hopeful lead free piezoelectric materials.

We report the brilliant piezoelectric and dielectric properties of (Na0.5K0.5)NbO3 (NKN)-based materials and consider a promising candidate as a lead-free piezoelectric ceramic. However, because of volatile characterization of potassium and sodium oxide, the difficulty of sintering condition of NKN ceramics has been significantly issued. Therefore, we focused on sintering aids. To suppress volatilization and improve the sintering condition, other perovskite type’s compounds and various sintering aids were added to NKN ceramics. We fabricated the 0.98(Na0.5K0.5)NbO3–0.02Li0.04(Sb0.06Ta0.1)O3 (0.98NKN–0.02LST) ceramic by conventional solid-state reaction, and investigated the effects of various sintering aids (Ag2O, CuO, CeO2, MgO, MnO, ZnO) on the piezoelectric, dielectric, and structural properties of the 0.98NKN–0.02LST ceramic. All samples showed more outstanding properties than NKN ceramics. These results indicate that the 0.98NKN–0.02LST ceramics doped with various sintering aids is a promising candidate as a lead-free piezoelectric ceramic.
