Crystallization　process　of　cordierite　glass-ceramics　containing　TiO2　as　nucleating　agent　was　studied　by　DTA,　XRD,　SEM　techniques　and　the　mechanical　properties　were　tested　as　well.　The　relationships　between　crystalline　types,　heat　treatment　methods　and　mechanical　properties　were　well　discussed.　The　results　show　that　with　the　increase　of　temperature,　magnesium　aluminotitanate　(MAT),　Β-quartz　solid　solution　(Β-QSS),　sapphirine,　spinel,　α-cordierite,　α-quartz,　cristobalite,　enstatite　are　precipitated　in　glass　in　sequence.　Mechanical　properties　of　this　material　mainly　depend　on　heat　treatment　methods.　When　the　glass　is　heated　at　850°C　for　2　h　and　then　at　1200°C　for　2　h,　excellent　mechanical　properties　can　be　obtained　and　its　flexural　strength　can　reach　to　over　340　MPa　steadily.
