ATZ ceramic is an Alumina Toughened Zirconia that is Hot Isostatically Pressed. Combining YTZP (Yttria – Tetragonal Zirconia Polycrystalline) ceramic with ultra high purity Alumina and then Hot Isostatically Pressing it, gives my ATZ ceramic transformation toughened properties as well as a toughness that is unheard of for ceramics. This is due to its martensite-type transformation mechanism of stress induction along with the introduction of ultra high purity alumina into its latice structure. Among the engineering ceramic materials, ATZ ceramic has some of the highest mechanical strengths and toughness of any ceramic material in the world. With a flexural strength near or equal to cemented carbides, it is the ultimate choice in zirconia ceramic materials.
