design of zirconia alumina ceramic ceramic loop durability

  • Zirconia Toughened Alumina - an overview |

    Zirconia particles are placed among alumina particles, filling some of the voids among alumina particles. This enhances durability as voids in a ceramic could lead to a reduction of strength and increased possibility of cracking. Table 13.1 shows the mechanical properties of pure alumina, zirconia and ZTA.
