Manganese　titanate　(MnTiO3)　powders　have　been　synthesized　by　a　sol-gel-hydrothermal　method　at　low　temperature　below　to　473　K　through　using　NaOH　as　mineralizer.　The　structural　character　of　as-synthesized　powders　were　characterized　by　X-ray　diffraction　(XRD),　scanning　electron　microscope　(SEM),　Fourier　transformed　infrared　spectroscopy　(FTIR)　and　Raman　spectroscopy.　The　results　indicate　that　the　as-obtained　powders　are　phase　pure　pyrophanite　MnTiO3　with　pie-shape　morphology.　The　electronic　properties　of　as-synthesized　powders　was　characterized　by　UV-vis　diffuse　reflectance　spectroscopy　(UV-vis),　which　shows　the　as-obtained　sample　has　a　significant　absorption　in　the　visible　region.　(C)　2004　Elsevier　B.V.　All　rights　reserved.
