Abstract
In this paper, CuSO4 and Na2SO3 are the main raw material, the cuprous oxide fine powder was prepared by chemical precipitation. A single variable method was used to study the effect of various factors on powder particle size, and we get the best reaction conditions. The fine power were obtained and analyzed in this concentration condition, the thermogravimetry, differential thermal, specific surface area and aperture diameter of the power by comparing the powder at certain temperature and concentration. We found that the cuprous oxide powder were up to the demand in a reaction temperature of 85℃ and the reaction concentration of 1.0mol/L. It can provide important technical basis for industrial production. According to the experimental design method and the design process, the sample powder with high purity and high temperature stability was prepared. Therefore, it is possible to produce the ideal fine powder cuprous oxide by chemical precipitation method. And with its raw material easy, the equipment requirements are low, easy to operate, product purity and others advantages.
