摘要

Bone cement, based on dicalcium phosphate dihydrate as initial powder and sodium polysilicate solution as hardening liquid, was developed. The apatite phase started to form 3-4 h after the cement preparation. The kinetics of phase transformations during the hardening process was investigated, applying the energy dispersive X-ray diffraction (EDXRD) technique for real time studies. The Fourier transform infrared (FTIR) spectroscopical, scanning electron microscopy (SEM) morphological studies and compressive strength test were carried out.
