| Abstract: |
| Chrysocolla was prepared by hydrothermal synthesis method with sodium silicate solution and copper nitrate solution as reactants. The effects of dropping order of reactants, stirring reaction temperature, temperature and time of hydrothermal reaction, and mineralizer on synthesis were investigated. The products were characterized by IR, XRD and chemical analysis. The results show that high-purity sky-blue chrysocolla is prepared under the following conditions including sodium silicate solution dropped into copper nitrate solution, stirring reaction temperature of 35 ℃, stirring reaction time of 4 h, dosage of mineralizer of 0.1 mol/L Na2SiO3 of 40 mL and 0.1 mol/L NaOH of 20 mL, hydrothermal reaction temperature of 120 ℃, and hydrothermal reaction time of 6 h. |
