Notes:
Porous CaO-P2O5-SiO2 monolithics with double-pore structure were prepared fromtetraethoxysilane, triethylephosphate and calcium nitrate by a sol-gel method. Polyethylene glycoland starch were used as mesopore-making agent and as macropore-making agent, respectively. Theporous monolithics, having mesopores with ~20 nm pore size and macropores with 7~20 μm poresize, could be formed from the removal of organic components after heated at 600°C for 2 hours.After soaked in simulated body fluid (SBF) at 37ºC for 7 days, bonelike apatite was formed on thesurface of the samples. The porous samples were degraded gradually in SBF solution
