On Morphology and Partical Size Conrol of (Y, Eu)2O3 Precursor

    Graphical Abstract
    • Abstract
  • The(Y, Eu)2O3 Precursor which is superior to commercial one on morphology was prepared by precipitation method of oxalic acid. The effect of reaction conditions on morphology and particle size of (Y, Eu)2O3 precursor was investigated. The results show the medium particle size of precursor was influenced mainly by these facts: concentration of rare earth solution, excessive amount of oxalic acid, concentration of ammonia, concentration of oxalic acid and temperature of reaction.
