ATZ ceramic powder is a composite material of nano-alumina and nano-zirconia. The ATZ produced by our company is classified according to the different alumina content and material properties to meet the needs of different customers. ATZ material has excellent low temperature aging resistance, better strength and performance in hydrothermal environment than yttrium oxide stabilized zirconia ceramics, especially in the moving hydrothermal parts, excellent wear resistance, chemical production of ATZ than the physical production has a more delicate grain, low sintering temperature, strength, toughness and wear resistance and other advantages.
