Polycrystalline yttria ceramics

The use of yttria ceramics as standalone materials for structural applications is rather limited by their poor mechanical properties. For example, the commercially available 99.9% polycrystalline yttria CeraDoy (Ceradyne Inc.) has a flexural strength of 99 MPa, a hardness of 5.85 GPa, and a fiacture toughness of 1.4MPam. The hardness and fracture toughness of polycrystalline yttria are virtually grain-size... [Pg.49]
