  • Process for producing ceramic green compacts by double layer compression
    Patent number: 5667548
    Abstract: 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.
