Zirconium oxide, also known as zirconia, is a popular material used in a variety of applications due to its superior strength, stability, and resistance to high temperatures. Synonyms for zirconium oxide include cubic zirconia, stabilized zirconia, zirconium dioxide, and yttria-stabilized zirconia (YSZ). Cubic zirconia is a synthetic gemstone used in jewelry and is the most well-known application of zirconia. Stabilized zirconia is used in the manufacturing of refractory products, foundry coatings, and dental prostheses. Zirconium dioxide is often used in the production of fuel cells, catalytic converters, and abrasive powders. YSZ is a common material used in the production of fuel cells for applications such as electricity generation in vehicles.
