Abstract
A novel method for preparing sols from metal oxide precursors by using inorganic salts as the peptizing agent is disclosed herein. Sol-gels prepared from the sols are also disclosed. Ceramic coatings, monoliths, bodies and are formed. These structures have a particle size of down to 0.0001 micron and are endowed with excellent packing characteristics as well as smoothness.
