Abstract
A method is proposed for the synthesis of nanoscale boehmite powder at low temperatures of hydrothermal treatment in 1.5 wt % HCl solution at 150 and 170°C and in water at 80, 100, and 130°C. The optimal parameters of hydrothermal treatment are found. The conversion stages of γ-Al2O3 to boehmite (AlOOH) are found; the process is solid-phase (topochemical). The physical and technological properties of boehmite nanopowder are studied. We have found that boehmite possesses similar properties despite the temperature of hydrothermal treatment.中文翻译:
