FeTiTaO6　ceramics　were　prepared　by　conventional　mixed　oxide　method,　using　the　pure　rutile　and　mixture　of　rutile　with　anatase　as　titanium　source.　The　phase　formation　and　morphological　evolution　of　FeTiTaO6　were　investigated　by　XRD　and　SEM.　The　dielectric　properties　were　also　measured.　The　results　show　that　with　pure　rutile　as　titanium　source,　the　prepared　FeTiTaO6　ceramics　exhibit　a　strong　relax　ferroelectric　feature,　while　using　the　mixture　of　rutile　with　anatase　as　titanium　source,　no　dielectric　peak　appears　in　ceramics.　Due　to　the　difference　between　the　two　crystalline　TiO2,　the　phase　transformation　occurs　in　the　calcining　process　and　the　prepared　FeTiTaO6　powders　have　the　different　reaction　activity,　which　further　affects　the　thermodynamic　process　of　ceramic　sintering,　resulting　in　the　different　dielectric　behavior.
