Mixed oxides containing La, Mg and Ta were prepared by the sol-gel methods A pure phase, La(Mg2/3Ta1/3)O3 was formed by calcining the gel at a low temperature ( < 1100°C). The gel powders calcined at 1100°C were made into pellets and sintered at 1500°C for 6 h. The room temperature dielectric constant and tangent loss for the ceramics were found to be 22.0 and 24.8 X 10-4, respectively, at 10 kHz. LMT was characterized by X-ray diffraction and shown to be hexagonal with lattice parameters a = 9.1844 Å and c = 16.8742 Å. The melting point of the phase was found to be ∼ 2000°C by the laser heated pedestal growth technique.
