Document Type and Number:
Japanese Patent JP2546870
Kind Code:
B2
Abstract:
A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material (5) to a shape-defining surface (3) of an expendable pattern (2). The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the material of the expendable pattern (2) combusts or volatilizes and thus establishes the shaped cavity mold. A molten parent metal (1) is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it. The ceramic body is recovered from the mold having a shaped surface replicating the shape-defining surface (3) of the expendable pattern (2).
