摘要
Behavior of Ca/P ceramics enhanced by MgAl//2O//4 in simulated body fluid (SBF) was studied. Results show that, biological apatite can precipitate on the surface of Ca/P composite ceramics, however, dissolution of the surface of Ca/P composite ceramics also occurs due to a kind of amorphous material which is produced through reaction of MgAl//2O//4 with Ca/P ceramics at elevated temperature; therefore, the behavior of Ca/P composite ceramics in SBF mainly depends on those two processes. Analysis of joint influence of those two processes show that low content of MgAl//2O//4 favors the formation of biological apatite, therefore, brings about higher bioactivity.
