Composition for preparing silicon-based ceramic core, aero-engine silicon-based ceramic core blade and preparation method of aero-engine silicon-based ceramic core blade
The invention belongs to the technical field of aeronautical materials, and particularly relates to a composition for preparing a silicon-based ceramic core, an aero-engine silicon-based ceramic core blade and a preparation method of the aero-engine silicon-based ceramic core blade. The composition for preparing the silicon-based ceramic core, provided by the invention, is prepared from the following components in parts by mass: 30 to 33 parts of 240-mesh quartz glass powder, 22 to 24 parts of 600-mesh quartz glass powder, 22 to 24 parts of 1000-mesh quartz glass powder, 16 to 20 parts of mineralizer, 0.5 to 1 part of yttrium oxide, 1 to 2 parts of mullite, 1 to 2 parts of cristobalite, 11 to 18 parts of paraffin, 1 to 2 parts of beewax, 0.3 to 1 part of polyethylene and 0.5 to 1 part of oleic acid. The composition for preparing the silicon-based ceramic core provided by the invention is easy to depoling and high in high-temperature strength, and the prepared aero-engine silicon-based ceramic core blade is high in yield.
