High fracture resistant alumina based alumina-zirconia ceramic composite (Al2O3 + ZrO2) is extensively used in space shuttle adiabatic ceramic engine and nuclear industries for high temperature resistant components. Alumina-zirconia ceramic composite (Al2O3 + ZrO2) possess higher fracture resistance and lead to high hardness and strength high wear resistance low thermal conductivity corrosion resistance and oxidation resistance during machining.
