  abstract = {In this study ceramic materials with an Al2O3-matrix toughened with different amounts of Ag nanoparticles (0.0, 0.5, 1.0, 2.0 and 3.0 wt. %) were fabricated. High energy milling was used to mix the materials in a planetary mill type, in which powder particles with sizes of ~300nm were obtained. With the milled powders, they were fabricated cylindrical samples by uniaxial pressing. Then, compacted samples were sintered in an electrical furnace at different temperatures (1400°C, 1500°C and 1600°C) and during different times (1, 2 and 3h). Microstructure observations were made with optical microscopy and scanning electron microscopy, observing in both cases dense composites with very fine microstructures. Concerning the measurement results of fracture toughness, which were estimated by the indentation fracture method, it was shown that the composites made by mean procedure present higher values than the average of the monolithic alumina, up to 400%. It was determined that the reinforcement mechanism of these materials is due to the deflection of cracks owing to metallic bridges formed by the silver used as alumina strengthener.},
