  • Method of manufacturing surface-modified ceramic powders with particles in the nanometer size
    Patent number: 5593781
    Abstract: In the method described, the degree of agglomeration of the nanometer-size particles can be readily checked, thus enabling dispersions of particles of this kind to be produced with high solids contents. The method calls for the unmodified powder to be dispersed in water and/or an organic solvent in the presence of a low-molecular organic compound including a functional group which can react and/or interact with groups present on the surface of the powder particles. The dispersant may subsequently be wholly or partly removed.
