A simple coprecipitation technique was used successfully to synthesize fine powders of MgNb{sub 2}O{sub 6} (MN) phase. An aqueous mixture of ammonium carbonate and ammonium hydroxide was used to precipitate Mg{sup 2+} and Nb{sup 5+} cations as carbonate and hydroxide respectively under basic conditions. This precipitate on heating at 750 deg. C produced MN powders. For comparison MN powders were prepared by the traditional solid state method. The phase content and the lattice parameters were studied by powder X-ray diffraction (XRD). Particle size and morphology of the particles were studied by scanning electron microscopy (SEM)
