Zirconia Ceramic Mechanical Properties
First used in the medical industry in 1969 zirconia has demonstrated exceptional biocompatibility with good tribological properties good aesthetic.
Zirconia ceramic mechanical properties. Zirconia stabilized with y2o3 has the best properties for these applications. It is also used in milling machines sliding parts and cutting blades. Therefore zirconia heads are less susceptible to the stress when contacting with metal cones. Data table covering the mechanical physical and electrical properties of technox zirconia ceramics.
Zirconia zro2 is a ceramic material with adequate mechanical properties for manufacturing of medical devices. It exhibits the highest mechanical strength and toughness at room temperature. All without the most common property of ceramics high brittleness. Zirconia is a very strong technical ceramic with excellent properties in hardness fracture toughness and corrosion resistance.
Zirconia exhibits great heat insulation as its thermal conductivity is less than 1 10 that of other ceramics. Zirconium dioxide also known as zirconia and zirconium oxide is a crystalline metal oxide that has found its way into the ceramics industry it is characterised by its high thermal resistivity mechanical resistance and abrasive properties. Zirconia has excellent mechanical properties with higher strength and fracture toughness than alumina. There are several grades of zirconia available the most common of which are yttria partially stabilized zirconia y psz and magnesia partially.
This may allow the realization of fixed partial dentures and permit a substantial reduction in core thickness. Details the attractive mechanical and physical properties of technox zirconia ceramics which lead to their application in cutting and slitting applications as rotary cutters and blade edges. The mechanical properties of zirconia are the highest ever reported for any dental ceramic. The introduction of zirconia based ceramics as restorative dental materials has generated considerable interest in the dental community.
