Composites were prepared from alumina with three different particle sizes and 7 to 21 vol% of an LZSA glass-ceramic composition (11.6Li2O-16.8ZrO2-68.2SiO2-3.4Al2O3,). Specimens were obtained by uniaxial pressing. The optimum sintering temperature and holding time were found to be different for each composite. Structural characterization (bulk density and crystalline phases); mechanical characterization (flexure strength, elastic modulus, fracture toughness, and fracture energy); and microstructural analyses were carried out. Fine-grained alumina-based composite containing 21 vol% of glass-ceramic (1470 ºC and 3 h holding time, 2.0% porosity) showed a fracture toughness of 4.93 MPa·m0.5, an elastic modulus of 210 GPa, a fracture energy of 57 J·m-2, and a flexural strength of 170 MPa, in very good agreement with values reported by the literature. An increase of 37-177% in the fracture energy due to 21 vol% LZSA addition in the alumina was achieved for the range of grain size obtained in this work. Even though the final composition included a glassy component, the observed mechanical properties confirmed the effectiveness of the crystalline phases that were formed from LZSA glass-ceramic in reducing the propagation of cracks. The results showed that the addition of the LZSA glass-ceramic improved the mechanical properties of alumina.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
