Abstract

Magnesia–Yttria nanocomposite powder was synthesized by new non-alkoxide sol-gel method. In this method, Y(NO₃)₃·6H₂O, Mg(CH₃COO)₂·4H₂O, Ethylene diaminetetraacetic acid (EDTA), Ethylene glycol (EG) were used as Y³⁺, Mg²⁺, chelating agent and solvent source, respectively. The influences of pH value and calcination temperature on phase evolution of samples have been investigated. As-synthesized magnesia– yttria nanocomposite powders were characterized by X-ray diffraction (XRD), field-emission scanning electron microscope (FESEM), energy dispersion spectrum (EDS), inductively coupled plasma (ICP), thermal gravimetric-differential thermal analysis (TG/DTA), the Brunauer-Emmett-Teller (BET) method and Fourier transform infrared (FTIR) analysis. The as-synthesized magnesia–yttria nanocomposite powder was consolidated by the cold press technique and sintered at 1400 °C for 2 h. The FESEM micrographs of sintered Magnesia– Yttria composite showed a uniform distribution of MgO and Y₂O₃ phases.
