Durch Kristallumwandlung gehärtete Zirkonium-Titan-Yttriumoxid-Keramik. |
摘要 |
Disclosed is the production of ceramic compositions consisting essentially of Zr02, titania, and yttria or rare earth oxides such as gadolina, ytterbia, neodinia, and ceria. Mole % concentration values as low as .25 mole % for yttria in the titania-zirconia body have been found to provide a hard and tough ceramic material. These compositions have been found to produce effective hard and tough ceramic bodies when mixed with refractory fibers and/or whiskers or hard refractory ceramics. |
