The pH Level Influence on Hydroxyapatite Phase Composition Synthesized with Hydrothermal Method

Аннотация

This paper reports the pH level influence on hydroxyapatite phase composition synthesized with hydrothermal method in Ca(OH)₂-H₃PO₄, Ca(NO₃)₂-(NH₄)₂HPO₄-NH₄OH, Ca(OH)₂-NH₄H₂PO₄.The obtained samples were studied with X-Ray diffraction, Fourier Transform Infrared (FTIR) and Raman spectroscopy. The one phase Ca₅H₂O₁₃P₃ high crystallinity hydroxyapatite was synthesized with hydrothermal method at pH equal to 11. The crystallinity degree was calculated from the X-Ray diffraction pattern and became 0.96. The increasing pH level from 7 to 11 provides obtaining one phase hydroxyapatite at pH level 11 instead the two phase Ca_9.04(PO₄)₆(OH)_1.68, CaHPO₄ at pH level 9 and CaPO₃(OH), Ca(OH)₂ at pH level 7.
