Fine ceramics zirconia (ZrO2) compatible with complex shapes

Among fine ceramics, it is widely used in areas where mechanical strength and durability are particularly required. It is also suitable for use at high temperatures, which was previously a drawback.

Zirconia is widely used as a material with excellent toughness at room temperature, making it suitable for parts that require impact resistance and wear resistance, and it is also used as an electrolyte for oxygen sensors. However, a drawback is that its structure changes with temperature fluctuations, making it unsuitable for high-temperature applications. We offer fully stabilized (8mol) zirconia that can be used at high temperatures, as well as black zirconia for halation prevention. Additionally, we leverage the thermal expansion rate of zirconia for integration with metals and macor, and we accept complex shape processing based on our long-standing experience in ceramics processing. Please feel free to contact us.
