| Abstract: | Using copper electrodes,cuprous oxide powder was prepared by electro-synthesis method in alkaline solution of sodium chloride. The operating conditions such as the comcentration and temperature of electrolyte,anode current density and additive were studied one by one. The optimum conditions for preparing cuprous oxide were established as follows:［NaCl］=260-290g/L,［NaOH］=0.5g/L(i.e.pH=12.1),temperature,80℃,anode current density,750～1000A/m2,［Na2Cr2O7］=0.05g/L. Under this condition,cuprous oxide powder well within GB1620-79 was obtained. |
