What is Synthesis, formation and characterisation of FeNbO4 powders about?
A modi®ed mixed oxide synthetic route has been developed for the synthesis of iron niobate, FeNbO 4 (FN). A rapid vibro-milling technique was employed, with the formation of FeNbO 4 phases investigated as a function of calcination temperature and dwell time by XRD and DTA. The particle size distribution of the calcined powder was determined by laser diraction techniques, and the morphology, phase composition and crystal structure determined via SEM, TEM and EDX. It has been found that the unreacted Fe 2 O 3 and FeNb 2 O 6 phases tend to form together with FeNbO 4 , with the latter appearing in both monoclinic and orthorhombic phases, depending on calcination conditions. It is seen that optimisation of calcination conditions can lead to a 100% yield of FeNbO 4 in an orthorhombic, a -PbO 2 -type phase.
