Electrical properties and microstructure were investigated on the effects of MnO₂ and the lead-free (Na0.44K0.52Li0.04)(Nb0.83Sb0.07Ta0.1)O₃ ceramics with the addition of MnO₂ were fabricated by a conventional mixed oxide method. A gradual change in the crystal and microstructure was observed with the increase of MnO₂ addition. For the NKN-LST-xmol%MnO₂ sintered at 1100℃, bulk density increased with the addition of MnO₂ and showed maximum value at addition 1.0mol% of MnO₂. Curie temperature of the NKN-LST ceramics slightly decreased with adding MnO₂. The dielectric constant, piezoelectric constant (d₃₃) and electromechanical coupling factor (kp) increased below 0.25mol% of MnO₂ addition, which might be due to the increase in density. The high piezoelectric properties = 145 pC/N, electromechanical coupling factor = 0.421 and dielectric constant = 2883 were obtained for the NKN-LST-0.25mol%MnO₂ sintered at 1100℃ for 4h.
