Abstract
Official abstract text for this publication.
Acicular boehmite nanoparticles, methods of making acicular boehmite nanoparticles, and composite materials that contain acicular boehmite nanoparticles are described. The acicular boehmite nanoparticles are prepared in a continuous hydrothermal reactor from a feedstock solution containing a soluble aluminum-containing precursor.
First claim
Opening claim text (preview).
We claim: 1. A method of making an acicular boehmite nanoparticle, the method comprising: providing a feedstock solution comprising an aluminum-containing precursor dissolved in an aqueous-based solvent at a pH no greater than 6, the aluminum-containing precursor being of Formula (I) Al(OH) w (R 1 ) x (R 2 ) y (R 3 ) z (I) wherein R 1 is a first carboxylate selected from a formate or acetate; R 2 is a second carboxylate that is different from the first carbo…
