This utility model discloses a ceramic auxiliary impeller for a composite ceramic pump, comprising an auxiliary impeller ceramic body, a metal frame, a metal hub, and a front cover plate. The auxiliary impeller ceramic body has a hub hole in its middle that mates with the metal hub. The interior of the auxiliary impeller ceramic body has a receiving cavity for accommodating the metal frame. The front end of the auxiliary impeller ceramic body has a cover plate cavity for inserting the front cover plate. The metal frame is circumferentially disposed on the outer surface of the metal hub. After inserting the metal hub into the hub hole and the metal frame into the receiving cavity, a resin-ceramic bonding layer is poured into the receiving cavity. Then, the front cover plate is placed into the cover plate cavity. The resin-ceramic bonding layer connects the auxiliary impeller ceramic body, metal frame, metal hub, and front cover plate into a whole.
