Study of the bioactivity of fluorophlogopite–whitlockite ceramics

Fluorophlogopite–whitlockite phase compositions containing ceramics were prepared using Egyptian raw materials. The in vitro studies confirmed the bioactivity of the prepared mixtures. Finely divided HA layer was formed on the surface of the ceramic samples after immersion in SBF. The morphology of finely divided HA grains was found to be needle-like crystalline aggregates. The contents of calcium cations measured in SBF increased on the seventh day, compared with the first day of immersion which is attributed to dissolution. The values of phosphorous cations were slightly reduced on the seventh day, compared with the first day of immersion that is attributed to the successive dissolution and precipitation.
