Abstract

The invention discloses a method for preparing nanometer erbium oxide by a reaction ball milling method. The method comprises the following steps of simultaneously putting erbium-containing inorganicsalt water solution, graphene oxide-containing alcoholic solution, surfactants, precipitants and grinding body zirconium oxide beads into a ball milling cavity; taking a reaction on various raw materials under the ball milling effect; forming a nanometer erbium oxide precursor; performing filtering, washing, drying and roasting to obtain high-purity high-dispersion nanometer erbium oxide. Throughthe application of the reaction ball milling method, the graphene oxide-containing alcoholic solution and the surfactants, the prepared nanometer erbium oxide has the primary particle diameter of 10 to 30 nm through TEM detection. The method has the advantages that the process is simple; the cost is low; the controllability is high; the product particle uniformity is obviously improved; no pollution is caused on the environment; the method is suitable for industrial production.
