Title:

PLASTICALLY DEFORMABLE AQUEOUS CERAMIC SLURRIES AND METHODS OF MAKING SUCH COMPOSITIONS

Document Type and Number:

WIPO Patent Application WO2001021545

Kind Code:

A8

Abstract:

A plastically deformable aqueous ceramic slurry wherein the ceramic particles have on the surfaces thereof a closely-packed anionic surfactant bilayer or an anionic/nonionic surfactant bilayer. Optionally, such ceramic particles have on the surfaces thereof a closely-packed cationic surfactant bilayer or a cationic/nonionic surfactant bilayer. Such slurries are produced by: a) dispersing ceramic particles in an amount of water to form an aqueous ceramic slurry; b) adding an anionic surfactant or a mixture of an anionic and nonionic surfactant to such slurry and, c) adjusting the pH value of such slurry to adsorb or the ceramic particle surfaces a closely-packed anionic surfactant bilayer or anionic/nonionic surfactant bilayer.
