英文摘要：

Ceramic core is one of the key components during high-performance aircraft engine turbine blades＇ manufacturing, which is the only way for the formation of engine hollow blade cavity structure. The quality of ceramic cores directly affects the performance of aircraft engines. In this paper, the researches at home and abroad on alumina ceramic cores were reviewed firstly from the aspects of the molding process, auxiliary raw materials, leach technics etc. Compared with the silica-based ceramic cores, alumina-based ceramic cores show superior qualities in performance and preparation process. Then, the problems as well as corresponding measures during the applications of alumina-based ceramic cores were indicated. At last, we presented some ideas on the development of alumina-based ceramic cores.
