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.
