氧化镍粉体的制备工艺研究

Nickel oxide powder can be used for the preparation of nickel oxide target. The performance of nickel oxide powder is related to the production cost and the performance of the target. In this paper, the main preparation parameters of nickel oxide powder, such as binder content, grinding time, sintering conditions, reflected the micromorphology of the powder through the change of preparation parameters, the change of apparent density, to guide the production of nickel oxide. It is found that the sphericity of powder and the apparent density of powder can be improved with the increase of binder content. Grinding can make the sphericity of the powder worse. With the increase of sintering temperature, the grain size of the surface of the sphere increases, but the sintering time has no obvious effect on the microstructure of the surface of the sphere. By comparing the influence of preparation parameters on the microstructure and apparent density, the optimum process parameters for preparing nickel oxide powder were determined.
