Abstract:
The preparation of porous B-tricalcium phosphate bioceramic ( PTCP) was improved with the adjustment of the constituents and the sintering-process. A new type of bioceramic material w ith good biological and mechanical properties was made. The compositions, microstructure and propert ies of PTCP were analyzed w ith TG- DSC( thermogravimet i-c differential scanning calolimete) , XRD( X - ray diffraction) , TEM( transmission electron microscope) , SEM( scanning elect ron microscope) and so on. The result indicates that the stearic acid burn sufficiently and gives out carbon dioxide and water vapor w hen slowly heated between 200℃and 400 ℃ .The porous structure like coral in β-TCP bioceramic is formed. Through crystallizat ion at 470℃ and 570℃ , more CaO- P2O5 glass-cement was converted into crystallite-glass, w hich is beneficial in improving the intensity of β-TCP bioceramic. PTCP can form a support action in bone imperfect section with good solubility.
