  • Method for producing a ceramic part with an internal structure
    Patent number: 6350404
    Abstract: A method for forming a ceramic part with an internal structure includes aqueous slip-casting and a polystyrene foam insert. An aqueous slurry is poured over the insert to form a green body. The insert is shaped to produce the desired internal structure upon being encased by the slurry. The insert is then removed from the green body by dissolving it in trichloroethylene. Because the polystyrene foam does not expand when exposed to trichloroethylene and rapidly dissolves, build up of shrinkage stress in the green body is avoided. The green body is then sintered to produce the ceramic part with an internal structure.
