Preparation of cuprous oxide reduction of small test and the designation of the Production
Abstract: This article outlines the characteristics of cuprous oxide (Cu2O) and the application of ultrafine particles in cuprous oxide, technology advances characterization techniques;research the company's existing products cuprous chloride as raw materials were prepared by liquid-phase reduction method of high purity nano cuprous oxide powder small test technology for the company's existing product development downstream of the high-end products, the use of XRD, EMS, IR of the product was characterized. Low production cost precipitation method, the equipment is simple, easy operation, good stoichiometry and grain size range of products has a wider distribution, which ensures that the cuprous oxide grain controllable. Based on small scale process and to consult relevant parameters, and then the material balance, heat balance for device selection based on plant layout, and finally by the CAD software to draw a flow chart, plant layout. In order to provide a reserve for the design technology of business process.
