Abstract
Rhodium vanadate an important catalytic compound was synthesized by solid state reaction route and characterized by X-ray diffraction. The standard molar Gibbs energy of formation of rhodium vanadate was determined using solid state electrochemical technique employing a calcia stabilized zirconia (CSZ) oxide ion conducting electrolyte. The Gibbs energy of formation was determined from electromotive force measurements carried out in the temperature range from 959 K to 1137 K.Magnetic measurements using a Vibration Sample Magnetometer (VSM) in the temperature range from 4 K to 300 K under the influence of a magnetic field of 1 kOe was carried out. The measurements concluded that the compound RhVO4(s) shows paramagnetic behavior. The magnetization measured at 1.8 K under a changing magnetic field shows a very narrow and symmetric loop that further reiterates the above conclusion.
