Реферат: TITLE METHOD FOR PRODUCING MOLD-SHAPED CERAMIC BODIES APPLICANT LANXIDE TECHNOLOGY COMPANY, LP INVENTOR Evans Allen LAROCHE, JR. ABSTRACT A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a gas-permeable, conformable material to a shape-defining surface of a shaped parent metal. The gas-permeable 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 parent metal melts and flows from the mold into a receptacle without disturbing the mold. Oxidation reaction product is then grown by oxidation of the molten parent metal with a vapor-phase oxidant to form an oxidation reaction product which grows into the mold cavity and is shaped by it. A ceramic body is recovered from the mold and has substantially the same shape as the pattern section of the original shaped parent metal.
