Abstract: Lead-free bismuth sodium potassium lithium titanatebarium titanate [0.885 (Bi1/2Na1/2)TiO3-0.05(Bi1/2 K 1/2)TiO3-0.015(Bi1/2Li1/2) TiO 3-0.05BaTiO3, BNKLBT-1.5] fibres have been fabricated by a powder-based extrusion method. The ceramic fibres with 400 μm diameter were well-crystallized after being calcined at 800°C and sintered at 1170°C. After being poled, the electromechanical coupling coefficient k33 of the fibre is 0.55 while other properties are comparable to those a ceramic disc. The BNKLNT ceramic fibres prepared by the powder-based extrusion method have good piezoelectric and ferroelectric properties and have potential to replace lead zirconate titanate (PZT) fibres in various device applications.
