To investigate its structure and ferroelectric properties, a sodium niobate-bismuth lithium titanate ((1-x)NaNbO3-x(Bi0.5Li0.5)TiO3) ceramic with a composition of x = 0.05 was created using a solid-state mixed oxide reaction method. Na2CO3, Nb2O5, Li2CO3, Bi2O3, and TiO2 were used to make the composite. The ((1-x) NaNbO3-x(Bi0.5Li0.5)TiO3) (x = 0.05) exhibits an orthorhombic crystal structure based on the X-ray diffraction pattern. The X-ray diffraction research was measured using an X-ray diffractometer. The morphological inspection is analysed using a scanning electron microscope (SEM). Ferroelectric measurements were performed using the P-E loop tracer. The coercive field (Ec) and remnant polarisation (Pr) of the ceramic sample were observed to rise with increasing applied voltage. Critical evidence from the combined structure and hysteresis loop analysis suggests that the ((1-x)NaNbO3-x(Bi0.5Li0.5)TiO3) (x = 0.05) ceramic is expected to be a potential new lead-free electronic material contender. Hence, ferroelectric materials have many applications, including capacitors, non-volatile memory, piezoelectric for ultrasound imaging and actuators, electro-optic materials for data storage applications, and thermistors.
