| Description |
Bioactive powders of silicon substituted hydroxyapatites containing 1.4-4.3 wt % Si were synthesized by precipitation from aqueous solutions of calcium nitrate and ammonium (sodium) hydrophospate. Tetra-ethoxysilane and sodium silicate in basic media were used as a source of silicon. Using scanning electron microscopy, surface morphology of the obtained products was studied. It has been found that procedure us-ing sodium silicate allows obtaining of materials with 100-200 nm particle size. Procedure that utilizes tet-raethoxysilane leads to 40-100 nm particles. Chemical, X-ray phase analysis and infrared spectroscopy of samples annealed at 900 °C indicate the formation of monophase crystalline products possessing apatite structure.
