Abstract:
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) wherein R R R w is in a range of 1.5 to 2.2; x is equal to at least 0.1; y is equal to at least 0.1; and z is in a range of 0 to 0.2; and passing the feedstock solution through a continuous hydrothermal reactor held at a temperature in a range of 150° C. to 180° C., wherein an effluent of the continuous hydrothermal reactor comprises the acicular boehmite nanoparticle.
