    2007-11-1 · Zirconia (ZrO 2) is a ceramic material with adequate mechanical properties for manufacturing of medical devices. Zirconia stabilized with Y 2 O 3 has the best properties for these applications. When a stress occurs on a ZrO 2 surface, a crystalline modification opposes the propagation of cracks. Compression resistance of ZrO 2 is about 2000 MPa.
