Phase and morphology evolution of (Na1-xKx)NbO3 powders related to calcinations and K2CO3 content

Sodium-potassium niobate ((Na1-xKx)NbO3) powders with x = 0.2, 0.4, 0.6 and 0.8 were prepared following the conventional mixed oxide method and characterized by TG-DTA, XRD and SEM techniques.The effects of calcination temperature, dwell time and K2CO3 content on phase formation behavior and morphol...
