Zirconium dioxide (ZrO₂), also known as zirconium oxide, is an important technical ceramic material and one of the most widely used high-performance ceramics. Due to its high melting point and excellent thermal and chemical resistance, zirconium oxide is particularly suitable for demanding applications at elevated temperatures.

A distinctive feature of zirconium dioxide is its different crystal modifications. With suitable stabilization, for example using yttrium oxide, the mechanical properties of the material can be specifically modified and improved. Stabilized zirconium dioxide is therefore frequently used for highly stressed technical ceramic components.

Zirconium oxide combines high hardness, wear resistance, temperature resistance and chemical stability. This makes the material suitable for applications in which conventional ceramic or metallic materials reach their performance limits.

The element zirconium is used both as zirconium metal and in the form of numerous technical compounds. While zirconium metal is important for specialized industrial applications, zirconium oxide plays a major role in high-performance ceramics, protective coatings, electronics and high-temperature components.

Would you like to buy zirconium oxide? The Evek GmbH online shop offers zirconium dioxide, zirconium metal and other technical materials for industrial applications. The zirconium price, zirconium metal price and zirconium price per kg primarily refer to metallic zirconium, while the price of ZrO₂ depends on purity, particle size, modification, stabilization and order quantity.
