Zirconium oxide ceramic rods (ZrO₂ ceramic rods) offer exceptional hardness, optimized thermal stability, and superior wear resistance. Designed for high-performance industrial applications, they ensure precise structural integrity, extended durability, and reliable operational efficiency.
Product Overview:
Zirconium oxide (ZrO₂) ceramic rods are a high-performance material known for their excellent resistance to high temperatures, wear, and corrosion. These rods are widely used in high-temperature, chemically corrosive environments, and applications requiring high strength. Zirconium oxide can exist in three crystalline forms and is typically white, but may appear yellow or gray if impurities are present. The manufacturing process requires ultrafine powder particles with a narrow particle size distribution.
