Boehmite Nanoparticles with Different Functional Properties for Preparing Products with Specific Parameters

摘要

The characteristics of boehmite nanopowders prepared by re-precipitation of aluminum trihydroxide, a sol-gel method by aluminum alkoxide hydrolysis, and hydrothermal synthesis from industrial aluminum powders are investigated. Boehmite nanopowder preparation method has a decisive effect on structure, dispersion, chemical and phase composition, and production properties. It is shown that when preparing products with specified parameters it is necessary to consider the difference in the effect of boehmite nanopowder on functional properties. Examples of the use of boehmite nanopowder from different producers in ceramic and catalyst technologies are provided.
