Abstract
We have developed a method for the preparation of boehmite (AlOOH) nanopowder with tailored properties (particle size from 10 to 40 nm, thermal conductivity below 0.02 W/(m K), specific surface area on the order of 65 m2/g, and loose bulk density in the range 0.02–0.04 g/cm3) by hydrothermal treatment of γ‑Аl2О3 nanopowder in a 1.5% HCl solution at 200°C. The steps of the process have been identified and it has been shown to be a solid-state (topochemical) transformation.中文翻译:
