Nanostructured Disaggregated Aluminum Hydroxide and Oxide Powders

Resumo

Results are provided for an experimental study of disaggregation of aluminum hydroxide (boehmite) powder prepared by hydrothermal oxidation of aluminum powder. The effect of heat treatment temperature, drying with heated steam, milling in ball and knife mills, treatment in rotary pulsating equipment, addition of surfactant on original powder disaggregation and preparation of nanostructured boehmite and aluminum oxide, are studied. Process parameters are determined for preparing nanostructured powders.
