We have obtained new lead-free ferroelectric ceramics based on potassium sodium niobate solid solutions. The densification of these ceramics has been successfully accomplished by using different oxides as sintering aids. Addition of MnO2 not only improves the densification process but also increases dielctric, ferroelectric and piezoelectric ceramics. Good results were obtained by substituing B-site perovskite lattice Nb5+ for Sb5+ and preparing the solid solutions with barium titanate BaTiO3.
