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