Synthesis of Y_2O_3 Nanopowder by Carbonate Method at Room Temperature

Y_2O_3 nanopowder is synthesized directly from YCl_3 solution of industry with precipitation through making supermicro-reactant by non-surfactant and the purity and particle diameter of Y_2O_3 nanopowder are controlled by the process. TEM micrographs show that the particles are ball and their average diameter is 30nm.Y_2O_3 nanopowder purity is 99.99% and the area per gram of Y_2O_3 nanopowder is 6060m~2/g.The results show that the diameters, purity and dispersion of Y_2O_3 nanopowder depend on the concentration of YCl_3 solution, surfactant concentration and the burn method. Y_2O_3 nanopowder can get when the concentration of YCl_3 solution is 0.1~0.6mol/L, surfactant concentration is 1.2×10~(-3)~6×10~(-3)mol/L and grade temperature is up to 700℃.
