Abstract

The glass-ceramic mainly containing fluorophlogopite is one of widely used dental ceramics. In the K2O-CaO-MgO-Al2O3-SiO2-F system, a new-type glass-ceramic containing fluorophlogopite Ca-mica has been synthesized. Its crystalline was studied by XRD and EDS. The fluorophlogopite whose formula postulated K1 − X CaX/2Mg3AlSi3O10F2 was its main crystalline. The microstructure of the glass-ceramic displayed typical machinable microstructure with lath like crystals isolated and interlocking with different aspect ratio. The material also showed better bending strength (228.11 ± 7.55 MPa). It took less than 12 minutes to fabricate a whole crown by dental CAD/CAM system with the glass-ceramic.
