摘要
讨论了不同浓度NH4H2PO4促凝剂对α-Ca3(PO4)2(α-TCP)水化和硬化的影响,测试了相应的硬化物凝固时间和机械强度。最后利用扫描电子显微镜,X-射线衍射仪分别对α-TCP-NH4H2PO4骨水泥硬化产物的物相和结构进行了探讨。
The authors discussed the effect of the set accelerator (NH4H2PO4 )on the hydration and hardening of α-Ca (PO4)2 (ie α-TCP), and tested the setting time and mechanical strength of the appropriate hardening products. Finally,the authors explored the phase and structure of the hardening products of α-TCP-NH4H2PO4 bone cement by using SEM and X-ray diffractometer
