多孔偏磷酸钙(CMP)陶瓷是使用原位自发泡方法制造的。研究了具有不同孔隙率和强度的多孔CMP陶瓷,并研究了制备工艺和所得材料的性能。在低成型压力(≤2.0MPa)或低加热速率(≤0.5°C min -1)的条件下,仅使用Ca(H 2 PO 4)2 ·H 2 O(MCPM)或Ca( H 2 PO 4)2(MCPA)作为原料可以被制成多孔生物陶瓷,而不会变形和没有成孔剂。在这项研究中,MCPA样品在80.0 MPa的压力下成型,加热速率控制在0.5°C min -1。所述合成生物材料显示出38.0%的孔隙率和48.0MPa的强度。

Shaped, composite bodies are provided. One portion of the shaped bodies comprises an RPR-derived porous inorganic material, preferably a calcium phosphate. Another portion of the composite bodies is a different solid material, preferably metal, glass, ceramic or polymeric. The shaped bodies are especially suitable for orthopaedic and other surgical use.
