Abstract：
Ceramic cores have been widely used for investment precision casting of turbine blades in aircraft engines and can help fabricate hollow structures in blades. In this paper, the application status of ceramic cores was investigated. Research on the fabrication process and common matrix materials was discussed, and the merits and demerits of ceramic cores fabricated with silica glass, fused alumina, zircon powder, and yttrium oxide were separately discussed.
