2. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   [11] [12] [13] Zirconia stabilized with yttria (yttrium oxide), known as yttria-stabilized zirconia, can be used as a strong base material in some full ceramic crown restorations. [12] [14] Transformation-toughened zirconia is used to make ceramic knives. [15] Because of the hardness, ceramic-edged cutlery stays sharp longer than steel edged ...

3. Yttria-stabilized zirconia - Wikipedia

   en.wikipedia.org/wiki/Yttria-stabilized_zirconia

   Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" ( Zr O 2 ) and "yttria" ( Y 2 O 3 ), hence the name.

4. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO 4). It is sometimes erroneously called cubic zirconium.

5. Zirconia toughened alumina - Wikipedia

   en.wikipedia.org/wiki/Zirconia_Toughened_Alumina

   It is a composite ceramic material with zirconia grains in the alumina matrix. It is also known in industry as ZTA. Zirconia aluminia (or zirconia toughened alumina), a combination of zirconium oxide and aluminum oxide, is part of a class of composite ceramics called AZ composites. Noted for their mechanical properties, AZ composites are ...

6. Tetragonal polycrystalline zirconia - Wikipedia

   en.wikipedia.org/wiki/Tetragonal_polycrystalline...

   Yttria blends of approximately 3% are called either tetragonal polycrystalline zirconia or tetragonal zirconia polycrystal (forming the initialisms TZP or TPZ) and have the finest grain size. These grades exhibit the highest toughness at room temperature, because they are nearly 100% tetragonal, but this degrades severely between 200 and 500 ...

7. Ceramic forming techniques - Wikipedia

   en.wikipedia.org/wiki/Ceramic_forming_techniques

   Methods for forming powders of ceramic raw materials into complex shapes are desirable in many areas of technology. For example, such methods are required for producing advanced, high-temperature structural parts such as heat engine components, recuperators and the like from powders of ceramic raw materials.

9. Zirconium - Wikipedia

   en.wikipedia.org/wiki/Zirconium

   Zirconium dioxide (ZrO 2) is used in laboratory crucibles, in metallurgical furnaces, and as a refractory material [13] Because it is mechanically strong and flexible, it can be sintered into ceramic knives and other blades. [51] Zircon (ZrSiO 4) and cubic zirconia (ZrO 2) are cut into gemstones for use in jewelry.
