METHODS AND MATERIALS FOR ATTACHING CERAMIC AND REFRACTORY METAL CASTING CORES

A slurry is used to secure a metallic casting core (212) to a ceramic casting core (210). The slurry may be introduced between the metallic and ceramic casting cores (212,210) and hardened. The slurry may comprise zircon and aqueous colloidal silica. Preferably the cores (210,212) are vibrated durin...

Summary:A slurry is used to secure a metallic casting core (212) to a ceramic casting core (210). The slurry may be introduced between the metallic and ceramic casting cores (212,210) and hardened. The slurry may comprise zircon and aqueous colloidal silica. Preferably the cores (210,212) are vibrated during the introduction, e.g. by a shaker table (202) which receives a fixture (204) for the cores (210,212).
