Abstract
A boehmite particulate material is disclosed. The material is formed by a process that includes providing a boehmite precursor and boehmite seeds in a suspension, and heat treating the suspension to convert the boehmite precursor into boehmite particulate material. The boehmite particulate material has an aspect ratio of not less than 3:1.
Claims14
A method for forming boehmite particulate material, comprising:
- providing a boehmite precursor and boehmite seeds in a suspension;
- and
- heat treating the suspension to convert the boehmite precursor into boehmite particulate material, the boehmite particulate material having an aspect ratio of not less than 3:1, wherein the boehmite seeds provide a nucleation site for the growth of the boehmite particulate material.
