▎ 摘  要

NOVELTY - Large-scale silicon-based ceramic core comprises ceramic powder, heat conducting agent, pore forming agent and plasticizer. The content of the heat conducting agent is 0.5-5 wt.% of the mass of the ceramic powder. The content of the pore-forming agent accounts for 3-15 wt.% of the mass of the ceramic powder. The content of the plasticizer accounts for 12-28 wt.% of the mass of the ceramic powder. USE - The large size silicon-based ceramic core is useful in field of precision casting. ADVANTAGE - The large size silicon-based ceramic core has excellent thermal conductivity, porosity, strength and porosity of the product, and improved production efficiency. The method is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing large size silicon-based ceramic core.
