Abstract: This invention relates to a new ceramic-metal composite body and a method for producing the same. Par­ticularly, a compliant layer composition is utilized for preventing the rupture of a ceramic article (1) and/­or the yielding or failure of a metal during the pouring, solidification and cooling of a molten metal which has been cast around the ceramic. A slurry compo­sition for the compliant layer (2) includes plaster of paris, a liquid vehicle and a filler material. The slurry composition is coated on the ceramic article (1) and thereafter is heat-treated to form a compliant layer (2). Ceramic-metal composite bodies comprising low strength hollow articles and high expansion coefficient metals may be manufactured according to the method of this invention.
