Abstract

Disaggregation of nanosized powders synthesized in liquid media is an urgent task of modern industry. On the example of nanoboehmite suspensions obtained by hydrothermal treatment of various precursors, there have been proposed new methods of disaggregation by introducing ammonium citrate or oxalate or microcrystalline cellulose into the suspension or by bubbling CO₂ through it. Subsequent heat treatment of the modified boehmite powder gives a γ-Al₂O₃ nanopowder, and its technical characteristics are reported.

纳米粉末的分解

摘要

在液体介质中合成的纳米级粉末的分解是现代工业的紧迫任务。由各种前体的水热处理而获得nanoboehmite悬浮液的例子中，已经通过引入柠檬酸铵或草酸盐或微晶纤维素到悬浮液中或通过鼓泡CO提出解聚的新方法₂通过它。修改后的勃姆石粉末的后续热处理给出的γ-Al ₂ ö ₃纳米粉末，其技术特性列。
