Abstract Glass-ceramics are polycrystalline materials obtained through crystallization of certain glasses. The control of crystallization and chemical composition allows one to obtain glass-ceramics with varied crystalline phases, crystalline fractions, crystal size, thus covering numerous properties. For the development and improvement of these properties, glass-ceramics have been used in numerous environments, such as in the aerospace industry, households, electronic circuits, acoustic systems and even as biomaterials.The main objective of this work is the development of a relatively tough and bioactive glass-ceramic, i.e. that shows a biological response when in contact with body fluids. For this goal, we will devise a new glass formulation with optimized microstructure by heat treatment, and thus obtain desired properties, such as high toughness (KC > 2,5 MPa.m1/2) and a high index of bioactivity (Ib> 3,1).(AU) | |
