The measurements of electric properties of Na[0.98]Li[0.02]NbO ceramics for stress-free or samples under stress have been carried out. It was found that incorporation of Li-cations (2% mol) in antiferroelectric NaNbO causes the induction of ferroelectric properties. It was also found that axial pressure shifts the phase transition and decreases the polarisation. These effects can be mainly connected with change in domain walls dynamics and with the switching of the polarisation under the action of axial pressure.
