Zirconia/graphite compound mold core was prepared by the coating, in which the silicon sol was used as binder and zirconia was used as refractory materials. The application feasibility of metal particles as a coolant in the solidification process was studied, and the application of metal particles as subsidiary coolant in the liquid metal cooling of directional solidification were analyzed and studied in this investigation. The conclusions can be drawn as follows: 1 The zireonia/graphite compound cores fabricated by brushing coating which was prepared by making silicon sol agglutinated zirconia as a refractory material were casteded at 800℃and 1000℃respectively, and the results show that the strength of the mold core is strong enough to meet the requirement of practical casting.
