Abstract

The raw Y₂O₃ powder was classified and graded based on modified co-sedimentation mathematical model, using the size distribution of W particles as the known condition. Y₂O₃-W continuous graded materials with the composition distribution index P values of 1.0, 0.7, 0.3 and 0.1 were prepared by co-sedimentation and hot-pressing. The results show that the Y₂O₃ powder consistent with the design requirements can be obtained by graduation method. The gradient continuity of materials can be verified by microstructure observation and hardness testing.
