摘要：

Two series of fluoro-alumino-silicate glasses, one with varying phosphate content (P2O5) and one with fixed phosphate content and varying fluorite (CaF2) content have been investigated as potential bioglass-ceramics. Compositions with intermediate phosphate contents that contained fluorite crystallized to fluoroapatite and mullite. Compositions with high fluorite contents exhibited a low liquidus temperature, were readily castable and crystallized by a bulk nucleation mechanism. The fluoroapatite phase with appropriate heat treatment formed as thin needle-like crystals with a high aspect ratio.
