Nano yttrium stabilized zirconia for ceramic toughening

Hangzhou Jiupeng New Materials

Although ceramic materials have many superior properties, such as high-temperature mechanical properties, chemical corrosion resistance, electrical insulation, high hardness, and wear resistance. However, due to its structure, ceramic materials lack the ability to slip and cause plastic deformation under stress like metals, which easily leads to defects, cracks, and high stress concentration, thus determining the essence of brittleness in ceramic materials.

Therefore, improving the brittleness of ceramic materials is a long-term concern for ceramic scientists. In recent years, fiber reinforcement and zirconia phase transition toughening have been proven to be two effective ways to improve the brittleness of ceramics and strengthen ceramics in practice

Ceramics sintered from nano yttrium stabilized zirconia powder for structural ceramics have become one of the main structural ceramics due to their excellent performance in phase transformation and toughening; In the research of nanocomposite materials, significant effects have been achieved by using nano yttrium stabilized zirconia as a dispersed phase matrix to enhance and toughen structural ceramics.
