Abstract：

The　effect　of　SiO2/Li2O　ratio　(in　mole)　on　the　structure　and　property　of　lithium　disilicate　glass-ceramics　was　investigated.　The　structure　and　mechanical　properties　of　the　specimenunder　nucleation　conditions　were　analyzed.　The　results　show　that　the　structure　and　property　of　glass　change　when　SiO2/Li2O　ratio　increases　from　2.0　to　2.4.　The　specimen　with　a　SiO2/Li2O　ratio　of　2.2　has　the　optimum　crystallization　and　mechanical　properties　oflithium　disilicate　glass-ceramics　(i.　e.,　a　bending　strength　of　(404±30)　MPa).　Also,　the　effects　of　nucleation　temperature　and　time　on　the　structure　and　mechanical　property　of　the　glass　with　a　SiO2/Li2O　ratio　of　2.2were　investigated.　In　the　preparation　process,　the　main　phase　in　this　glass　after　first　heat　treatment　is　lithium　metasilicate.　The　main　phase　in　this　glass　after　second　heat　treatment　is　lithium　disilicate,　which　possesses　a　fracture　toughness　of　3.58MPa•m-1/2.　©　2019,　Editorial　Department　of　Journal　of　the　Chinese　Ceramic　Society.　All　right　reserved.
