Na0.99Li 0,01 NbO3 ceramics were prepared by solid-state reaction method. The samples were characterized by X-ray diffraction, microstructure and dielectric permittivity measurements. The X-ray diffraction analysis showed that samples have a single phase of perovskite structure with orthorhombic symmetry. Microstructure investigations revealed crystalline structures in grains. It was found that dielectric properties of Na99Li0.01NbO3 ceramic are sensitive to the applied axial pressure. This includes the shift of phase transformation, diffuseness of the ϵ (T) profile and reduction of the thermal hysteresis. These effects can be caused by change in domain structure and anisotropy of crystallities, the change of inter-ionic distances and change in density of defects under the action of axial pressure.
