Abstract Scope Lithium metasilicate glass-ceramic, Li<sub>2</sub>SiO<sub>3</sub>, for CAD/CAM (Computer-aided design/Computer-aided manufacturing) machining has unparalleled aesthetic properties for the manufacture of dental restorations. This material is milled to obtain partial or total replacement components to natural teeth. After milling, the prostheses are submitted to heat treatment to the transformation of Li<sub>2</sub>SiO<sub>3</sub> in lithium disilicate, Li<sub>2</sub>Si<sub>2</sub>O<sub>5</sub>. In this work, Li<sub>2</sub>SiO<sub>3</sub> samples were heat treated at 820°C at different holding times from one to nine minutes under vacuum. Samples were characterized by X-ray diffraction, SEM (Scanning Electron Microscopy), hardness, fracture toughness, biaxial flexure test. The results indicate a progressive increase in Li<sub>2</sub>SiO<sub>3</sub>-Li<sub>2</sub>Si<sub>2</sub>O<sub>5</sub> transformation, hardness around 580 HV, a slight increase in fracture toughness (1.8 to 2.0 MPam<sup>1/2</sup>) and increased bending resistance associated with Li<sub>2</sub>Si<sub>2</sub>O<sub>5</sub> rise, which is composed of grains with high aspect ratio.
