The Centrifugation Casting of Nd:YAG Ceramics Melt by Combustion Synthesis

Abstract:

In this paper, Nd:YAG ceramic was prepared by combustion synthesis with centrifugation 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 A1₂O₃). The YAG could be obtained as the ratio between the Y₂O₃ and A1₂O₃ 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.
