  • An overview of zirconia ceramics: Basic properties and ...

    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. Orthopedic research led to this material being ...

  • All you need to know about Ceramic(Zirconia) implants

    Ceramic particles are the latest technology. Their fine-grained structure causes smaller fragments to break during the grinding process, which gives them a 50-200% longer life than Zirc; Zirconia flag discs remove material faster than ceramic flag discs. Ceramic flap discs operate cooler than zirconia and alumina flap discs, reducing heat build-up.
