Mg-Free Precursors for the Synthesis of Pure Phase Si-Doped α-Ca3(PO4)2
On this paper, methods to obtain Mg-free reagents for synthesizing pure phase Sistabilized α-TCP were established. The Mg contents of synthesized reagents were considerably lower than those in commercially available reactants. Pure Si-doped (2.5 at.-% of P by Si substitution) α-TCP was obtained by solid state reaction from synthetic reagents at temperature as low as 1200°C. When commercial reagents were employed for the solid state synthesis, a mixture of α- and β-TCP was obtained even when the solid state reaction was conducted at 1300 °C.
