摘要：

This　study　aimed　to　develop　a　glass-ceramic　based　on　the　SiO2-Al2O3-B2O3-P2O5　system.　The　effect　of　the　nucleating　agent　TiO2　and　the　alkali　oxide　Na2O　on　the　crystallisation　behaviour　of　SiO2-Al2O3-B2O3-P2O5　glass-ceramics　was　studied　using　XRD,　DTA,　and　SEM.　Results　showed　that　when　TiO2　content　was　16　wt%,　only　the　anatase　crystallised　producing　a　white　glass-ceramic.　When　the　TiO2　content　was　＞16　wt%,　both　rutile　and　anatase　formed,　which　produced　a　yellowish　colour.　When　the　TiO2　content　was　2O　content　was　2O　content　was　10　wt%,　rutile　and　anatase　crystallised.　When　the　Na2O　content　was　＞12　wt%,　rutile,　anatase　and　brookite　were　produced.　Therefore,　the　contents　of　TiO2　and　Na2O　must　be　controlled　at　16　and
