制备了ＣａＯ－Ｐ２Ｏ５系生物水泥样品，并研究了它的水化过程。用Ｘ射线衍射（ＸＲＤ）和扫描电镜（ＳＥＭ）分析和观察了不同组成的样品的结晶相和显微结构，测定了固结样品的力学性能。根据不同阶段的化学反应式，可以解释生物水泥的水化胶凝机理。羟基磷灰石形成一连续界石，其间仅混有少量小气孔。固化后的样品具有一定的强度和硬度。 CaO-P2O5 biocement samples were prepared and its hydration process was studied. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to analyze and observe the crystal phases and microstructures of samples with different compositions, and the mechanical properties of the consolidated samples were determined. According to the chemical reaction formulas of different stages, the hydration gelation mechanism of bio-cement can be explained. Hydroxyapatite forms a continuous boundary with only a small number of small pores in between. The cured sample has a certain strength and hardness.
