CHEMICALLY DELAMINATED MICA CONTAINING MINERAL

摘要

A mineral comprises a chemically delaminated weathered mica having a principal X-ray reflection at approximately 10 Angstroms characteristic of the mica basal spacing. The mineral may be produced by washing a suspension of weathered mica having a principal x-ray reflection at 10 Angstroms with a solution of intercalating ions e.g. organoammonium ions and with water in order to swell the weathered mica, mechanically shearing the swollen weathered mica, and separating components having a thickness greater than 500 Angstroms from the suspension so formed. The dispersion so formed may be used in the production of paints and coatings, or for electrophoretic deposition onto a metallic surface e.g. a wire conductor, in order to provide a high temperature insulation.
