| Abstract | ||
| Development of new glass filer of the composite is very important in dentistry due to their physical, mechanical and mainly anti-caries properties. In this research synthesis four new series of glass as filler. This filler usually consist of a fusion of aluminosilicate glass modified with other elements, and they contain large quantities of fluorine, (SiO2, Al2O3, AlF3, CaF2, NaF and AlPO4 (wt. %)). The method of preparing (Calcium-Fluoroaluminosilicate Glass) powder was carried out by medium temperature method. These series of glass characterized by X- ray diffraction XRD, Fourier transform infrared spectroscopy FTIR, Scanning electron microscopy SEM and differential thermal analysis DTA. XRD show the Crystallite size between (20-25 ) nm .The partial size of glass also find by using BET method. The morphology of glass measured by SEM. DTA/TG indicated that Calcium-Fluoroaluminosilicate Glass had better thermal stability than other glasses, the structures of the obtained glasses compared to the commercial material was also studied using FTIR measurements. | ||
