Abstract: A partial oxalate route has been developed for the synthesis of lead iron niobate, Pb(Fe1/2Nb1/2)O3 (PFN) powder. An oxalated iron niobate (FeNbO4) was employed as a key precursor with the formation of PFN phase investigated as a function of calcination temperature and dwell time by TG-DTA and XRD. The morphology of the calcined powder was determined via SEM. It has been found that the unreacted FeNbO4 and PbO phases tend to form together with PFN depending on calcination conditions. However, single phase PFN powder was successfully obtained for a calcination temperature of 900°C for 4 h.
