Figure 1.9 (a) Appearance of granulated Al2O3‐Y2O3 powders by spray drier and (b) internal structure of Al2O3‐Y2O3 powder compact after uniaxial press under 20 MPa.
The powder compact showed in the above figure is further pressed in CIP (cold isostatic press) machine at 140 MPa. Then, the pore size distribution of this sample after CIP was measured by using the mercury penetration method. The result is shown in Figure 1.10. The pore diameter of the sample using a binder with good crushing characteristics is concentrated at 30–40 nm, but large voids of μm size are detected in the other samples without a binder, resulting in structure defects (which induce light scattering sources at the end product). Once large structural defects are formed, it is difficult to completely remove them even by high‐pressure sintering techniques such as HP (hot press) and HIP (hot isostatic press) treatments.
