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 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 includes plaster of paris, a liquid vehicle and a filler material. The slurry composition is coated on the ceramic article and thereafter is heat-treated to form a compliant layer. Ceramic-metal composite bodies comprising low strength hollow articles and high expansion coefficient metals may be manufactured according to the method of this invention.
