Formation of convoluted silica precipitates during amorphous phase separation in the Ca-3(PO4)(2)-Sio(2)-MgO system
Dispersed aggregates of peculiar morphology have been obtained in phase-separated glasses of the system Ca-3(PO4)(2)SiO2-MgO, where the separated phase is amorphous silica, The formation of such convoluted aggregates is tentatively explained in terms of a fast coalescence process of initial isolated quasi-spherical droplets which behave as a dispersed phase in an emulsion-like system.
