Dielectric　zinc　magnesium　titanate　(ZMTO)　was　synthesized　by　a　facile　co-precipitation　method　using　TiOSO4　as　the　Ti　source.　The　decomposition　and　phase　evolvement　of　the　as-prepared　precipitates　during　heat　treatment　were　characterized　by　thermogravimetry　analysis　(TGA)　and　Fourier-transforming　infrared　(FT-IR)　spectroscopy.　X-ray　diffractometry　shows　that　different　pH　levels　have　a　significant　influence　on　the　crystallization　of　the　as-prepared　precipitate　due　to　the　magnesium　doping　content.　SEM　images　and　EDS　data　show　that　fine　hexagonal　(Zn,　Mg)TiO3　powders　with　a　Mg　doping　content　of　2.29at.%　could　be　obtained　at　a　pH　of　9　and　a　calcination　temperature　of　800°C.　After　sintering　at　1000°C,　hexagonal　(Zn,　Mg)TiO3　demonstrated　a　dielectric　constant　of　26-24　along　with　a　low　dielectric　loss　of　9.82×10-4-6.35×10-4　at　measurement　frequencies　between　108　and　109Hz.　©　2013　Elsevier　B.V.
