摘要：
The introduction of Ga//2O//3 into alkaline zincate solutions lowers the solubility of ZnO considerably, especially in the region of equilibrium of the liquid phase with the hydrated sodium zincate double salts. The solubility of ZnO decreases with decrease of the alkalinity of the solution for 20-25 to 8-10 mass % Na//2O. The best conditions for concentrating gallium in solutions for subsequent separation can be obtained at Na//2O contents not exceeding 10-12%. The density and viscosity of the solutions increase with increasing alkalinity. The conductivity decreases with increasing Na//2O and Ga//2O//3 concentrations.
