Preparation and characterization of calcium-fluoroaluminosilicate glass fillers for dental composite

الملخص EN

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.
