摘要: The well known slip casting process for the production of ceramic green parts, in which hardening is achieved by water removal with porous molds, is characterized by disadvantages in terms of strength, shrinkage during drying and problems with cracking during drying. The present invention avoids these disadvantages and produces ceramic green parts by changing the surface potential of powder particles in the slip instead of by removing water. Further more the coagulation strength is increased by adding polymers or extremely fine divided colloidal particles.

摘要: The invention concerns the field of slip casting for producing green compacts. The disadvantage of state-of-the art slip casting is among others the need for removing the water through porous molds, the resulting shrinkage and the tendency of the green compact to form shrinkage cracks. These disadvantages are eliminated by internally coagulating by compression the double layer of solid slip particles, so that the green compact may be solidified without the need for removing the water.
