摘要：

A CaO-SiO2-P2O5-CaF2 glass powder hardened within 4 min when mixed with an ammonium phosphate solution to form CaNH4PO4.H2O. After it had soaked in a simulated body fluid for 3 d, forming hydroxyapatite, the cement showed a compressive strength of 80 MPa. Implanted into a rat tibia, the mixed paste formed a tight chemical bond to the living bone within 4 weeks. Such a bioactive cement could be useful not only for fixing various kinds of implants to the surrounding bones but also, by itself, as a bone filler.
