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.

摘要

提出了一种在150和170℃下在1.5wt％的HCl溶液中以及在80、100和130℃下在水中进行低温水热处理的纳米级勃姆石粉末的合成方法。找到了水热处理的最佳参数。的转换级的γ-Al ₂ ö ₃勃姆石（AlOOH的）被发现; 该过程为固相（拓扑化学）。研究了勃姆石纳米粉的物理和技术性能。我们发现尽管水热处理温度高，勃姆石仍具有相似的性能。
