Evidence of phase heterogeneity in sol-gel Na0.5K0.5NbO3 system

Original language description

Na0.5K0.5NbO3 thin films have been synthesised via a sol-gel route using commercially available ethoxides of sodium, potassium and niobium. X-ray diffraction confirmed that film crystallisation occurred at >= 600 degrees C, but extra peaks indicated thepresence of secondary phase(s). The thin films displayed non-ferroelectric polarisation hysteresis loops. Evidence of phase heterogeneity was found from detailed analyses of the thermochemistry of the NKN precursor gels which showed multiple heating DTAexotherms for crystallisation around 480-550 degrees C. Additionally, heating DTA endotherms and cooling exotherms for NKN gels around 800-850 degrees C confirm the presence of a second phase
