Abstract
Abstract Polycrystalline samples of lithium tellurate Li2TeO4, were prepared by a high-temperature solid-state reaction technique. A preliminary X-ray structural study of the compound reveals the formation of a single phase orthorhombic compound at room temperature. Detailed studies of dielectric constant as a function of temperature and frequency suggest that the compound undergoes two phase transitions at −3°C and 62°C respectively. Variation of dc resistivity with temperature shows that the conductivity of the material increases with the rise in temperature.
