HIPped Yttria Tetragonal Zirconia Polycrystal (YTZP) from CoorsTek is a high-performance ceramic material known for its exceptional strength and toughness. This material features ultrafine tetragonal grains that enhance its mechanical properties, making it suitable for demanding applications. YTZP exhibits superior load-bearing capabilities and can achieve finer surface finishes, which is beneficial for precision components. The material is characterized by a high flexural strength of up to 1720 MPa and a compressive strength of 2500 MPa, indicating its robustness in structural applications. Additionally, YTZP has low thermal conductivity and a coefficient of thermal expansion similar to cast iron, which helps reduce stress in ceramic-metal assemblies. Its high volume resistivity and dielectric properties make it suitable for electrical insulation applications. Overall, HIPped YTZP is ideal for applications requiring high mechanical performance, wear resistance, and thermal stability, making it a strong candidate for engineers seeking durable ceramic solutions.
Yttria (yttrium oxide, Y2O3) is a rare-earth ceramic which exhibits both exceptional plasma resistance and an aptitude for high-temperature applications. Yttria is often used to stabilize other ceramic compositions like zirconia.
CoorsTek Exyria™ yttria can be formed into both solid parts and coatings for parts requiring exceptional corrosion resistance. Applying a PlasmaResist™ coating to compatible ceramic and metal components creates a corrosively inert barrier of pure yttria.
