摘要：Fluoroaluminosilicate glass was prepared from recycled low alumina glass, with the additions of AlF3 and CaF. That was to provide a cheap source of proper glass required to prepare glass ionomer cement GIC. Three batches of the fluoroaluminosilicate glass were prepared with different additions of CaF varied at the expense of AlF3. i.e., the glass was prepared with three different CaO contents. The prepared glasses were used as an essential part of GICs. It was found that a crystalline phase (fluorapatite) appeared as part of the set cement matrix. The XRD of the set cements indicated that the crystalline fluorapatite increases with the increase of the CaO content of the starting fluoroaluminosilicate glass. The increase of the CaO content also led to an increase in the density of the set cement and its compressive strength. In addition, the working and setting times were increased too. Finally, the set cements where shown bioactive.
