以微孔低晶方解石块体为前驱体，通过溶解-沉淀反应的组成转变制备了低晶B型碳酸盐磷灰石（CO（3）Ap）块体。换句话说，通过将Ca（OH）（2）压块碳酸化制备的微孔低结晶方解石块通过在60 ℃下暴露于1（-3）Na 2 HPO 4溶液中14天来进行磷化。mol.dm XRD、FT-IR和SEM分析表明，方解石块体完全转变为B型CO 3Ap，并保持其宏观形貌。低结晶B型CO 3Ap块的径向拉伸强度约为5.4 MPa，与低结晶方解石块的0.73 MPa相比，该值高得多。低结晶度B型CO 3Ap块由于其无机化学组成和结晶度与骨非常相似，可能是一种理想的骨替代物。(C)2010年，日本陶瓷协会。All rights reserved.
Low crystalline B-type carbonate apatite (CO(3)Ap) block was fabricated by compositional transformation based on dissolution-precipitation reaction using microporous low crystalline calcite block as a precursor. In other words, microporous low crystalline calcite block prepared by carbonation of Ca(OH)(2) compact was phosphoridated by exposing to 1 mol.dm(-3) Na2HPO4 solutions at 60 degrees C for 14 days. XRD, FT-IR and SEM analysis showed that calcite block completely transformed into B-type CO3Ap keeping its macroscopic morphology. Diametral tensile strength of the low-crystalline B-type CO3Ap block was approximately 5.4 MPa, and this value was much higher when compared with the low-crystalline calcite block, 0.73 MPa. Low crystalline B-type CO3Ap block fabricated in this method could be an ideal bone replacement due to its close similarity in its inorganic chemical composition and crystallinity to bone.
