| Abstract: | The various factors which influence the sizes and coagulation of the high purity nanometer Er 2O 3 powder particles have been studied systematically in this article,and the influence mechanisms have been discussed theoretically.Simultaneously the economical and stable method of preparation of high purity nanometer Er 2O 3 powder has been set up.The particles obtained by this method are spherical,the sizes are from 20 to 100nm.The amounts of impurities Ca and Mg decreased to 30% compared with the raw material of Er 2O 3. |
