摘要
The present disclosure generally relates to a ceramic core comprising predominantly mullite, which is derived from a precursor comprising alumina particles and siloxane binders. Free silica is present in the ceramic body, but is largely unavailable for reaction with metal alloys used in investment casting. Methods of making cast metal articles are also disclosed.
