Apatite-Leucite Micro/Nano Crystals from Aluminosilicate Glasses for Dental Applications
Needle-like apatite-leucite glass-ceramics were synthesized in the SiO2-Al2O3-Na2O-K2O-P2O5 CaO-CaF2 system. Four glass batches were prepared by varying SiO2/P2O5 ratio, then melted and quenched. Crystallization was studied in compacted powder samples at different temperatures. Glasses were characterized for chemical bonding by FT-IR, phases and crystal structure by XRD, microstructure by SEM and hardness and fracture toughness by Vickers microhardness.
