✦ Synopsis

A novel hydrothermal

alkoxide method is presented for the preparation of stable, aqueous dispersions of fairly monodisperse, charged colloidal boehmite needles. A polymer coating procedure for the needles is described which leads to sterically stabilized dispersions in organic solvents.
