A ceramic with a high fracture toughness K-IC that is close to the respective values of cast iron and Mg alloys has beenfabricated by microwave sintering of GdAlO3 and ZrO2 into composite materials of different molar fractions; for the 80/20 composite (see Figure for an SEM image) K-IC reaches the remarkable value of 17.5 Mpa m(1/2). Such composites may become extremely valuable for structural applications in advanced technologies.
