Soda lime glass beads were chemically treated by either an aqueous solution of NaOH (3mol/l) or a hydrogen peroxide solution (30vol%) containing TaCl₅ in 5×10^-3mol/l or by both of them. The treated samples were soaked up to 14 days in a simulated body fluid (SBF): Na⁺ 142.0, K⁺ 5.0, Ca²⁺ 2.5, Mg²⁺ 1.5, Cl^- 147.8, HCO₃^- 4.2, HPO₄^2- 1.0, SO₄^2- 0.5 (in 10^-3mol/l), or in another solution 1.5 times as concentrated as SBF (1.5SBF). The SBFs were kept at 36.5°C and at 7.25 in pH. Apatite was deposited on the samples treated with the NaOH solution, the H₂O₂/Ta solution, and both of them before soaking in 1.5SBF. Ta(V) ions were present on not only the samples treated with the H₂O₂/Ta solution but those treated with both NaOH and the H₂O₂/Ta solutions. It was concluded that Ta(V) ions on the surface layer had ability of inducing apatite deposition, and the ability was enhanced by the coexistence with silanol groups.
