Zirconium oxide ceramic sheets (ZrO₂ ceramic sheets) offer superior mechanical strength, optimized thermal stability, and excellent chemical resistance. Designed for high-performance industrial applications, they ensure precise structural integrity, extended durability, and reliable functionality.
Product Overview:
Zirconium oxide (ZrO₂) ceramic sheets are a high-performance material known for their excellent high-temperature resistance, wear resistance, and corrosion resistance. These sheets are widely used in applications requiring high strength and durability. Pure zirconium oxide is typically white, but may appear yellow or gray when containing impurities. Zirconium oxide exists in three crystal forms, and the production process requires powders with good dispersion and fine particle size to ensure consistency and stability in various industrial applications.
