Abstract
Physical and mechanical properties of a glass-ceramic belonging to the LZS (Li2O-SiO2- ZrO2) system were investigated by dilatometric analysis, differential thermal analysis, X-ray diffraction and measurements of density, hardness, bending strength, modulus of elasticity and fracture toughness. The obtained glass-ceramics showed ZrSiO4 and Li2Si2O5 as main crystalline phases, relative densities between 84 and 99%, maximum hardness, bending strength, modulus of elasticity and toughness of 8±0.5 GPa, 214±20 MPa, 115±0.42 GPa and 3.65±0.21 MPa.m1/2, respectively. © (2014) Trans Tech Publications, Switzerland.
