Large-size silicon-based ceramic core and preparation method thereof

HUANG FUQIANG / QIAO JINGWEI

The invention relates to a large-size silicon-based ceramic core and a preparation method thereof. The large-size silicon-based ceramic core is prepared from the following raw material components: ceramic powder, a heat conduction agent, a pore forming agent and a plasticizer, the content of the heat conducting agent accounts for 0.5 wt%-5wt% of the mass of the ceramic powder, the content of the pore forming agent accounts for 3wt%-15wt% of the mass of the ceramic powder, and the content of the plasticizer accounts for 12wt%-28wt% of the mass of the ceramic powder.

本发明涉及一种大尺寸硅基陶瓷型芯及其制备方法，所述大尺寸硅基陶瓷型芯的原料组分包括：陶瓷粉体、导热剂、造孔剂和增塑剂；所述导热剂的含量为陶瓷粉体质量的0.5wt%～5wt%，所述造孔剂的含量占陶瓷粉体质量的3wt%～15wt%，所述增塑剂含量占陶瓷粉体质量的12wt%～28wt%。
