dc.description.abstract	Lead-free ferroelectric ceramic oxides; KxNa1-xNbO3 (x = 0.45, 0.50 and 0.55) have been prepared using solid-state reaction technique by varying K/Na ratio. Their crystal structures have been investigated using XRD and Raman spectroscopic techniques at room temperature (RT). Rietveld refinement analysis on XRD data suggest the monoclinic crystal structure having Pm space group for K0.45Na0.55NbO3 and orthorhombic crystal structure with Amm2 space group for both K0.5Na0.5NbO3 and K0.55Na0.45NbO3 respectively. The composition driven structural phase transition of the KxNa1-xNbO3 is seen by the splitting of the mode near 191 cm-1 as well. The presence of prominent central peak (CP) reveals the order-disorder nature of the ferroelectric phase transition of the KxNa1-xNbO3.	en_US
