Dispersibility and Gelcasting Process of BN-Al2O3 -Y2O3 System

Keywords： dispersibility

The influence of dispersants and decentralization condition on rheological properties and gelcasting of BNA12O3-Y2 O3 slurry was discussed, and the thermodynamics of cross-linking process was studied. The results show that PAA is more effective and proper density of cross-linking can form unitary, stable gelinite system.
