摘要：
The beta-TCP granules with the range of diameter from 314 mu m to 800 mu m were prepared. The beta-TCP/HAP composite bioceramics were prepared by dipping beta-TCP discs made from the granules in HAP sol. The component and morphology of the ceramics were observed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) respectively. The compressive strength of specimens was tested by Testometric M350-20KN. The results show that the samples can be calcined at 1150 degrees C without phase transformation of beta-TCP to alpha-TCP by doping the beta-TCP with 1wt% MgO. And the compressive strength of the composite ceramics reaches 24MPa.
