Among the engineering ceramic materials, my HIPed YTZP has some of the highest mechanical strengths and toughness at normal temperatures.  It will go through phase transformation and slowly lose its properties at elevated temperatures (above 300 degrees C). It is relatively easy to be combined with metals because its coefficient of thermal expansion is close to that of metal. It is an ideal material to use for industrial knives because of the small, tight grain structure.
