Preparation of Nanosized La2CuO4 Particle by Chemical Precipitation Method and Its Thermoelectrical Properties

  Nanometer La2CuO4 particles have been prepared using chemical precipitation method.The reaction mechanism,microstructure and phase composition of the samples were investigated by TG-DTA,XRD,SEM.The XRD results showed that pure La2CuO4 phase can be obtained by calcining the La-Cu-O-H precursor powders at 900 ℃ for 2 h,and the impurity phase will appear in the La2CuO4 ceramic as increasing the sintering temperature over 1200 ℃.La2CuO4 ceramic samples sintered at 950 ℃ for 6 h exhibit good thermoelectric properties.Seebeck coefficient can reach 714 μV/K,and power factor is about 2.33 × 105 W/mK2.
