HIPped Yttria Tetragonal Zirconia Polycrystal (YZ-110 HS) from CoorsTek is a high-performance ceramic material known for its exceptional mechanical properties. It features a density of 6.07 g/cm¬= and offers a flexural strength of 1720 MPa at 20¬8C, making it suitable for applications requiring high strength and toughness. The material exhibits a compressive strength of 2500 MPa and a fracture toughness of 8.5 - 10.0 MPa m¬O, indicating its ability to withstand significant stress without failure. This zirconia variant is partially stabilized with yttria, which enhances its load-bearing capabilities and allows for finer surface finishes. It is particularly effective in severe-service environments due to its excellent wear resistance and corrosion resistance. The thermal conductivity is low at 2.2 W/mK, and it has a coefficient of thermal expansion of 10.3 x 10,Ū,Å?/¬8C, which is comparable to cast iron, minimizing stress in ceramic-metal assemblies. Overall, YZ-110 HS is an ideal choice for applications in industries such as oil and gas, industrial tooling, and other environments where durability and performance under extreme conditions are critical.
Zirconias have a unique crystal structure which combines extreme strength, high fracture toughness, and excellent wear resistance. CoorsTek has engineered transformation toughened formulations with zirconia crystal structures which expand when a micro-crack is formed — preventing further crack growth and arresting brittle failure.
CoorsTek zirconias, including our high-performance Technox® zirconia brand, are ideal for extreme mechanical environments, particularly impact prone applications. Certain zirconia compositions provide enhanced fatigue loading resistance.
