Article Preview

This work has achieved a novel self-setting biphase porous calcium phosphate cement (CPC). This biphase porous CPC is mainly formed by α-tricalcium phosphate (α-TCP) and β-tricalcium phosphate (β-TCP). The influence of the weight percent (wt%) of β-TCP of the powder was studied. The setting time is mainly 10-30min, and increasing with the weight percent of β-TCP. Powder ray diffraction (XRD) analysis showed that most α-TCP have turned to low-crystallinized HA after immersed in Simulated Body Fluid (SBF) of 37°C for 7 days. SEM observation showed that the resultants are mainly formed with micropores and microcrystallites, and more micropores turned out in cements with more β-TCP after immersed in SBF for 8 weeks.
