Abstract

A series of vanadate substituted hydroxyapatite was directly prepared by a simple hydrothermal method at low temperature (110-200 °C) in NaOH solutions for 14 h. The apatite samples were characterized by powder X-ray diffraction, ICP chemical analysis, nitrogen physisorption, TEM, and FTIR measurements. The vanadate/phosphate hydroxyapatite solid solution, i.e., Ca₁₀(VO₄)_x(PO₄)_{6 - x}(OH)₂ (xε{lunate}I = 0, 1, 2, 3, 4, 5, and 6), had a single phase of apatite structure. The lattice parameters increased linearly with increasing V content (x) with obeying the Vegard's law. All Ca₁₀(VO₄)_x(PO₄)_{6 - x}(OH)₂ (x = I) samples showed the OH vibration band around 3560 cm^{- 1}. The white apatite samples were column crystals with length of about 40-100 nm and width of about 25-40 nm.
