Zirkoniumdioxideverbindingen

Zirkoniumdioxideverbindingen refers to chemical compounds that contain zirconium dioxide, also known as zirconia. Zirconium dioxide (ZrO2) is a highly stable and refractory ceramic material. Its unique properties, such as excellent hardness, chemical inertness, and high melting point, make it valuable in various applications.

These compounds are often employed in high-temperature environments. For instance, stabilized zirconia, where other oxides like yttrium oxide or calcium oxide are added to prevent phase transitions at high temperatures, is used in thermal barrier coatings for gas turbines and jet engines. Its low thermal conductivity protects the underlying metal components from extreme heat.

In the field of dentistry, zirconium dioxide-based materials have gained significant popularity. They are used for crowns, bridges, and dental implants due to their biocompatibility, strength, and aesthetic qualities, mimicking the appearance of natural teeth. Their resistance to corrosion and wear further contributes to their suitability for oral applications.

Zirconium dioxide compounds also find use in solid oxide fuel cells (SOFCs) as an electrolyte. The ionic conductivity of certain stabilized zirconia at high temperatures allows for efficient energy conversion. Furthermore, they are utilized in oxygen sensors, ceramic knives, and as a pigment in glazes and enamels. The versatility of zirconium dioxideverbindingen stems from its robust chemical and physical characteristics, enabling its use in demanding industrial, medical, and technological sectors.
