The silicon-substituted hydroxyapatite (Si-HA) with three different Si-substitution levels were synthesized via aaqueous precipitation method, in the absence of any surfactants and organic solvents. The composition of the Si-substituted HA phases and effect of silicon substitution on the crystal structurewere investigated by Rietveld refinements from powder X-ray diffraction data. The results show that the final compounds are oxy-hydroxyapatites, a chemical formula for the Si-substituted HA phases with indication of the incorporated silicate amount is proposed.
