ABSTRACT:
A method of preventing gravity-induced deformation of a ceramic green body. The method comprises providing a ceramic green body and disposing the body in a fluid medium bath having a density that is greater than or equal to that of the ceramic green body. The green body is suspended and floats freely in the fluid medium, and deformation of the green body due to its own weight is prevented. Outer or peripheral portions of the ceramic green body may also be stiffened when the fluid medium bath comprises an aqueous salt solution comes into contact with the green body and causes gelation of a binder within the ceramic green body.
