| Abstract |
The aim of this study is to explore the effects of quenching and milling processing on
setting property of calcium phosphate cement (CPC). For this purpose, non-quenched α-tricalcium
phosphate (α-TCP) and quenched α-TCP were synthesized and their corresponding cement systems
were prepared. The particle size of α-TCP powder was introduced as a variable. Then, setting
properties of these CPC systems were estimated. By a comparison between non-quenched CPC and
the quenched one, it is found that milling processing mainly influences the initial setting stage by
decreasing reactant particle size whereas the quenching treatment affects the final setting stage by
changing α-TCP content, which supports that CPC setting initially depends on the surface area of
reactants and subsequently on the diffusion through the hydrated layer formed around the reactants. |
