Partially Stabilized Zirconia (PSZ) components are considerably more expansive than alumina and other oxide ceramics. However, PSZ components have unique properties such as extremely high fracture toughness, high thermal expansion, high flexural strength (MOR), and low thermal expansion. With a high fracture toughness and MOR, PSZ components resist crack propagation, are less brittle, and able to hold a sharp edge. The high thermal expansion of PSZ components make it easier to join metal to steel due to a low thermal conductivity. PSZ components act as thermal insulators. Some typical applications are dental implants, knives, guides, and pump and valve components for abrasive solutions and slurries.
