The properties of biologically active glasses in the system SiO2−P2O5−MgO−CaO were studied. Crystalline hydroxyapatite (HA) and β-wollastonite (β-W) were used after heat treatment (1100C). The influence of the glass particle size (0.071–2.5 mm) and of glass powder (d50=15.1 μm) on the behaviour of the products during differential thermal analysis was followed. These analyses indicated that the β-W probably originates from surface nucleation, and HA from bulk nucleation. The differentiation was confirmed by calculation of the Avrami parameters (n) with the Pi-loyan-Borchardt analytical method. For HA and β-W, the calculated values ofn were 2.96 and 1.91. The surface-nucleated glasses exhibited predominant bidimensional crystal growth.
