Kerámiazirconia

Kerámiazirconia refers to zirconia-based ceramics. Zirconia, or zirconium dioxide (ZrO2), is a highly versatile ceramic material known for its exceptional strength, toughness, and biocompatibility. In its pure form, zirconia undergoes phase transformations upon cooling, which can lead to cracking. However, through the addition of stabilizing oxides such as yttrium oxide (Y2O3) to form yttria-stabilized zirconia (YSZ) or magnesium oxide (MgO) to form magnesia-stabilized zirconia (MgSZ), these detrimental phase transformations are suppressed, resulting in a stable and robust material.

These stabilized forms of zirconia exhibit remarkable properties, including high fracture toughness, wear resistance, and a high melting point. These characteristics make kerámiazirconia suitable for a wide range of demanding applications. In the dental field, it is widely used for fabricating crowns, bridges, and implants due to its aesthetic qualities, strength, and biocompatibility, which minimizes allergic reactions.

Beyond dentistry, kerámiazirconia finds utility in industrial settings. Its wear resistance makes it ideal for components in pumps, valves, and cutting tools. Its high thermal insulation properties also lend themselves to applications in refractories and thermal barrier coatings. The development of advanced processing techniques, such as powder metallurgy and additive manufacturing, continues to expand the possibilities for kerámiazirconia.
