The centrifugation casting of Nd:YAG ceramics melt by combustion synthesis

摘要：

　　In this paper, Nd:YAG ceramic was prepared by combustion synthesis with centfifugation casting.Combustion temperature and pressure were calculated under adiabatic hypothesis, and measured experimentally by W/Re thermocouple and piezometer, respectively.The combustion temperature and pressure decreased with increase of the content of diluents (Y2O3 and Al2O3).The YAG could be obtained as the ratio between the Y2O3 and Al2O3 reached 3:5.Phase composition and microstructures of the derived products were analyzed by XRD, SEM and EDS.The results show that the other reaction product TiN and a small quantity of gas and oxide impurity were not completely separated from YAG melt under centrifugal force so that transparent YAG ceramic was not obtained in this work.
